摘要：
Two approaches were used to synthesize two resins with different pore structures. In one way, the [sbnd]CH<inf>2</inf>Cl groups in macroporous chloromethylated polystyrene resin were transformed to methylene bridges, and achieved a hypercrosslinked resin with plentiful micropores (denoted GQ-06). In the other way, 50% of the [sbnd]CH<inf>2</inf>Cl groups in chloromethylated polystyrene resin was used to produce micropores, while the residual 50% of the [sbnd]CH<inf>2</inf>Cl groups was reacted with 2-aminopyridine, and prepared another resin with double pore structure of hypercrosslinked resin and macroporous resin (denoted GQ-11). The adsorption of salicylic acid (SA) on GQ-11 was investigated using GQ-06 as the reference adsorbent. The effect of pH on the adsorption of SA on GQ-06 was consistent with the dissociation curve of SA. The maximum adsorption capacity of SA on GQ-11 was observed at the solution pH of 2.64. The greater adsorption rate of SA on GQ-11 than that of GQ-06 was attributed to its double pore structure. The multifunctional adsorption mechanism of anion exchange and hydrophobic interaction resulted in the larger equilibrium capacity of SA on GQ-11 than that of GQ-06. GQ-06 and GQ-11 could be regenerated by absolute alcohol and 80% of alcohol −0.5 mol/L of sodium hydroxide aqueous solution, respectively. ©2017 Elsevier B.V.

摘要：
On account of the high toxicity of nitrobenzene, 1,2‐dichloroethane was used as solvent. A novel water‐compatible hyper‐cross‐linked resin functionalized with amino‐group (denoted as GQ‐04) was synthesized to remove salicylic acid (SA) in aqueous solution. The maximum adsorption capacity of SA onto GQ‐04 was observed at pH of 1.88. The adsorption capacity increased with the increasing salt concentration. The adsorption kinetic data obeyed the pseudo‐second‐order rate equation and the adsorption isotherms can be characterized by Freundlich model. The intraparticle diffusion was the main rate‐controlling step. The saturated adsorption quantity of SA was up to 119.9 mg·mL‐1 according to the dynamic adsorption at 293 K. The resin could be regenerated by the 6 BV mixed solution of 80% ethanol and 0.5 mol/L NaOH. The size matching and hydrogen bonding between GQ‐04 and SA and the micropore structure resulted in the larger adsorption capacity in comparison with XAD‐4 and H103 resin. © 2012 Wiley Periodicals, Inc.

摘要：
A hyper-cross-linked polymeric adsorbent with "CH<inf>2</inf>phenolCH<inf>2</inf>" as the cross-linked bridge (denoted GQ-05), and another hyper-cross-linked polymeric adsorbent with "CH<inf>2</inf>p-cresolCH<inf>2</inf>" as the cross-linked bridge (denoted GQ-03) were synthesized to reveal the effect of the steric hindrance of micropores in the hyper-cross-linked polymeric adsorbent on adsorption capacity and adsorption rate of p-nitroaniline (PNA) from aqueous solution. The results of adsorption kinetics indicated the order of the adsorption rate GQ-05>GQ-03. The pseudo-first-order rate equation could describe the entire adsorption process of PNA onto GQ-05 while the equation characterized the adsorption process of GQ-03 in two stages. The order of the adsorption capacity GQ-05>GQ-03 was demonstrated by thermodynamic analysis and dynamic adsorption. The steric hindrance of micropores in the hyper-cross-linked polymeric adsorbent was a crucial factor for the order of the adsorption capacity and adsorption rate. ©2014 Elsevier B.V.

摘要：
Different functional group modified hyper-cross-linked polymeric adsorbents H103, GQ-1, GQ-2 and GQ-5 were synthesized from macroporous crosslinked chloromethylated styrene-divinylbenzene copolymers. Phenol was selected as a hydrogen bonding donator. The object of this work was to explore the effect of hydrogen bonding receptor in micropores of adsorbent on adsorption capacity. Results showed the BET surface area and pore volume followed the order H103 > GQ-5 > GQ-2 > GQ-1 while the adsorption capacity of phenol onto the four hyper-cross-linked polymeric adsorbents followed the order GQ-1 > GQ-2 > GQ-5 > H103. The density functional theory indicated that hydrogen bonding receptor in micropores of the adsorbents was a crucial factor for the adsorption capacity order. ©2016 Elsevier Inc.

摘要：
The macroporous polydivinylbenzene/poly(methyl acrylate) interpenetrating polymer network (PDVB/PMA IPN) was prepared by the sequential suspension polymerization method, and was modified to be hydrophobic-hydrophilic macroporous polydivinylbenzene/poly (sodium acrylate) IPN (PDVB/PNaA IPN) by converting the PMA to PNaA under the condition of base. The effects of different mass ratio of the two networks and different cross-linking degree of the second network on the pore structure and adsorption capacity of PDVB/PNaA IPN resin were studied. The PDVB/PNaA IPN resin whose adsorption quantity is the biggest was chosen to study further. The pore structure, the weak acid exchange capacity, the water retention capacity, and the swelling ability of PDVB/PNaA IPN resin were measured. The study focused on the adsorption isotherms of berberine at different temperatures. Isosteric adsorption enthalpy, adsorption Gibbs free energies can be calculated according to tSh1ermodynamic functions. The results show that the saturated adsorption quantity of berberine is up to 109.4 mg ml<sup>-1</sup> (wet resin) by the way of dynamic adsorption and desorption experiment. The resin could be reused by the mixture with 0.5% sodium chloride and 80% ethanol. On the one hand the hydrophobic PDVB in the PDVB/PNaA IPN resin has the ability of adsorption using π-πinteraction, and on the other hand the hydrophilic PNaA in the PDVB/PNaA IPN resin has the ability of adsorption using ion exchange interaction. An important conclusion can be drawn that the PDVB/PNaA IPN resin has a promising application prospect in extracting and separating quaternary ammonium type alkaloids such as berberine. ©2009 John Wiley &Sons, Ltd.

摘要：
Graphene sheets (GS)@manganic manganous oxide (Mn 3 O 4 ) nanocomposites were prepared via a simple solvothermal process. [email protected] 3 O 4 /nafion (Nf) film modified glassy carbon electrode (GCE) was fabricated and applied for the detection of dopamine (DA) without the interference of ascorbic acid (AA) at the low working potential. The prepared nanocomposites ([email protected] 3 O 4 ) were characterized by X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FT-IR), and the morphology of different electrodes was characterized by scanning electron microscopy (SEM). The electrochemical properties of the modified electrode (GCE|[email protected] 3 O 4 /Nf) were investigated by electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and current-time method (i-t curve). Under the optimized experimental conditions, the i-t curve showed a linear dependence on DA concentrations ranging from 1.0×10 -6 to 1.3×10 -3 M (R=0.9985) with a detection limit of 8.0×10 -8 M (S/N=3). The proposed method was used to detect DA in real pharmaceutical samples using the standard addition method without additional sample pre-treatment with satisfactory results, which showed great promise for screen-determination of DA in real samples. © 2015 The Authors.

摘要：
将氯球中-CH_2Cl转化为亚甲基交联桥,合成微孔丰富的超高交联树脂(命名为JX-06)。同时将氯球中50%的-CH_2Cl转化为亚甲基交联桥,50%的-CH_2Cl与邻氨基吡啶反应,合成既具有超高交联树脂孔结构和大孔树脂孔结构,又具有邻氨基吡啶功能基的复合孔结构树脂(命名为JX-11),对比研究JX-06树脂和JX-11树脂对2,4-D酸的吸附性能。实验结果表明,JX-06树脂吸附2,4-D酸的吸附量随pH值的变化规律与2,4-D酸分子比(2,4-D酸分子在2,4-D酸分子和2,4-D酸离子总和中所占的比)随pH值的变化规律相一致。JX-11树脂在pH值为3.23时对2,4-D酸的吸附量最大。疏水效应和阴离子交换的多重吸附导致JX-11树脂对2,4-D酸的吸附量大于JX-06树脂。复合孔结构使JX-11树脂比JX-06树脂对2,4-D酸有更高的吸附速率。经5次吸附解吸循环, JX-06树脂对2,4-D酸的吸附量略有减小,而JX-11树脂对2,4-D酸的吸附量则保持稳定。

摘要：
The objective of this work was to study the comparison of the adsorption performances of phenol in aqueous solution onto H103 resin and XAD-4 resin. Experimental results showed that the molecular form of phenol is favorable for the adsorption. The adsorption capacity of phenol onto H103 was much larger than that of XAD-4 due to its average pore diameter. The pseudo-first-order rate equation can characterize the adsorption of phenol onto H103 and XAD-4. The rate constant k<inf>1</inf> for XAD-4 is greater than the one of H103 at the same condition, consistent with the shorter required time for XAD-4. ©(2012) Trans Tech Publications, Switzerland.

摘要：
Comparative adsorption of glyphosate from aqueous solution by 2-aminopyridine modified polystyrene resin (denoted GQ-08 resin), D301 resin and 330 resin was investigated with respect to influencing factors, salinity resistance and mechanism. Results showed the maximum adsorption capacity of glyphosate onto the three resins was observed at pH of 2.51, and glyphosate was adsorbed in the form of HOPO2-CH<inf>2</inf>NH2+CH<inf>2</inf>COOH and HOPO2-CH<inf>2</inf>NH2+CH<inf>2</inf>COO<sup>-</sup>. The adsorption capacity of glyphosate onto the three resins followed the order 330 resin >D301 resin >GQ-08 resin, consistent with their total exchange capability order. GQ-08 resin exhibited excellent salinity resistance. Salinity resistance of GQ-08 resin resulted from the hydrogen bonding for the adsorption of glyphosate, while 330 resin and D301 resin exhibited the single adsorption mechanism of anion exchange. ©2015 Elsevier B.V.

摘要：
Hydrophobic-hydrophilic macroporous polydivinylbenzene/polymethylacrylethylenediamine IPN (PDVB/PMAEM IPN) was synthesized indirectly through the strong forced compatibility. The effects of the hydrophobicity of adsorbate on the adsorption of salicylic acid and 5-sulfosalicylic acid onto the hydrophobic-hydrophilic PDVB/PMAEM IPN were investigated. PDVB/PMAEM IPN exhibited greater adsorption capacity of salicylic acid than that of 5-sulfosalicylic acid. The absolute values of Delta H, Delta G and Delta S of the adsorption of salicylic acid onto PDVB/PMAEM IPN were greater than those of 5-sulfosalicylic acid, indicating the adsorption of salicylic acid onto PDVB/PMAEM IPN was more welcome. Adsorption mechanism proved that greater adsorption capacity of salicylic acid onto PDVB/PMAEM IPN than that of 5-sulfosalicylic acid was attributed to the stronger hydrophobicity of salicylic acid.

摘要：
A new effective fluorescent sensor based on rhodamine was synthesized, which was induced by Cu<sup>2</sup> in aqueous media to produce turn-on fluorescence. The new sensor 1 exhibited good selectivity for Cu<sup>2</sup> over other heavy and transition metal (HTM) ions in H<inf>2</inf>O/CH <inf>3</inf>CN(7:3, v/v). Upon addition of Cu<sup>2</sup>, a remarkable color change from colorless to pink was easily observed by the naked eye, and the dramatic fluorescence turn-on was corroborated. Furthermore, kinetic assay indicates that sensor 1 could be used for real-time tracking of Cu<sup>2</sup> in cells and organisms. In addition, the turn-on fluorescent change upon the addition of Cu<sup>2</sup> was also applied in bioimaging. ©2012 Elsevier B.V. All rights reserved.

摘要：
A novel water-compatible microporous and mesoporous hyper-cross-linked resin modified with phenolic hydroxyl group (named as GQ-03) was synthesized to remove aniline in aqueous solution as compared with XAD-4. The maximum adsorption capacity of GQ-03 emerged at the molecular state for both aniline and p-cresol while the pH dependency trend of aniline adsorbed onto XAD-4 was accordant with the dissociation curve of aniline. The ionic strength influenced the adsorption obviously. The pseudo-first-order rate equation could describe the adsorption process of aniline onto GQ-03 in two stages while this equation could characterize the entire adsorption process of XAD-4. The adsorption isotherms could be correlated to the Freundlich model, higher KF and n values for GQ-03 than XAD-4. The breakthrough capacity and the total adsorption capacity of GQ-03 and XAD-4 was up to 47.2 mg mL−1 and 28.3 mg mL−1, 271.7 mg mL−1 and 115.6 mg mL−1, respectively. The size matching between the pore diameter of GQ-03 and the molecular size of aniline, and hydrogen bonding between GQ-03 and aniline resulted in the larger adsorption capacity.
