摘要：
Two approaches were used to synthesize two resins with different pore structures. In one way, the [sbnd]CH2Cl 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]CH2Cl groups in chloromethylated polystyrene resin was used to produce micropores, while the residual 50% of the [sbnd]CH2Cl 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 −0.5mol/L of sodium hydroxide aqueous solution, respectively. © 2017 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：
According to the planar structure and the small molecular size of theophylline (TP), a novel hyper-cross-linked polymeric adsorbent with high microporous surface area (denoted GQ-06) was synthesized and its adsorption to TP was explored from aqueous solution. The results showed that GQ-06 possessed a high microporous surface area of 1223 m2/g and bimodal pore size distributions. The equilibrium adsorption capacity of TP on the five polymeric adsorbents followed an order as: XAD-4 < NDA-88 < H103 <NDA-150 <GQ-06, which was in agreement with the order of the microporous surface area. The adsorption as a function of the solution pH was accordant with the dissociation curve of TP from aqueous solution. The equilibrium adsorption capacity of TP on GQ-06 increased with increasing of the ionic strength due to the predominant contribution of the hydrophobic effect. The pseudo-first-order rate equation described the adsorption in two stages according to the bimodal pore size distributions. The adsorption isotherms were correlated to the Freundlich equation. The breakthrough capacity and the total capacity of TP on GQ-06 were up to 45.9 and 105.8 mg/mL respectively, and it could be regenerated by 4 BV of anhydrous ethanol. © 2016 Elsevier Inc.

摘要：
用LVJ-NF102聚酰胺纳滤膜在LJ-2540ST卷式膜中试设备中进行纳滤截留水体中磺胺二甲基嘧啶实验,考察操作时间、操作压力、磺胺二甲基嘧啶浓度和离子强度等因素对纳滤膜截留磺胺二甲基嘧啶的影响。结果表明,LVJ纳滤膜对磺胺二甲基嘧啶的截留率100 min后基本稳定;随操作压力的增加,LVJ纳滤膜通量和对磺胺二甲基嘧啶的截留率都增大;随着溶液中磺胺二甲基嘧啶浓度的增加,LVJ纳滤膜通量下降,对磺胺二甲基嘧啶的截留率先增大后维持不变;随溶液中离子强度的增加,LVJ纳滤膜通量和对磺胺二甲基嘧啶的截留率都减小。在磺胺二甲基嘧啶浓度为28.2 mg/L、操作压力为0.4 MPa条件下,LVJ纳滤膜5 min可使溶液中磺胺二甲基嘧啶截留82.7%。

摘要：
A heteropolyanion-containing polypyrrole/carbon nanotube modified electrode has been fabricated through entrapment of phosphomolybdic acid (H 3PMO12O40) in polypyrrole (PPy) film on multi-walled carbon nanotubes (MWNTs) modified gold electrode. The electrochemical behavior and the electrocatalytic property of the modified electrode were investigated in acidic solution. Compared with the H 3PMo12O40/PPy/gold electrode, the H 3PMo12O40/PPy/MWNTs/gold electrode has shown enhanced electrocatalytic property to the reduction of nitrite. Steady-state amperometry has been applied to characterize the modified electrode as an amperometric sensor for the determination of nitrite. Effects of PPy film thickness and MWNTs concentration on the current response of the modified electrode for the detection of nitrite have been investigated and discussed. Under the optimized conditions, a linear range from 5.0 × 10-6 to 3.4 × 10-2 M has been observed for the H3PMo 12O40/PPy/MWNTs/gold electrode with a sensitivity of 1214.1 mA M-1 cm-2 and a detection limit of 1.0 × 10-6 M according to a signal-to-noise ratio of 3.

摘要：
Benzil is an important photosensitive initiator of organic synthesis intermediates,medicinal intermediates and ultraviolet solidified resin (UVresin),and is usually prepared by oxidizing benzoin, The oxidizers and methods reported are mainly;(PhCH_2Et_3N)~+Br~-/(PhCO)_2O_2/MeCN~[1],DMSO/(COCL)_2 CH_2CL_2~[2],CrO_3·CH_3NH_2·HCl/Al_2O_3~[3], the metallorganic compound~[4],microwave radiation~[5],etc.The reaction conditions of some methods are harsh, the toxicity is heavy, the reaction reagent is expensive, the preparation is difficult, the aftertreatment is tedious or the conversion ratio of materials is low.Cupric compound is a kind of weak oxidizer.Up till now there is only the report of oxidizing benzoin with cupric sulfate-pyridine~[6] with cupric acetate-acetic acid~[7].This paper studies the problem of oxidizing benzoin by using cupric nitrate, cupric chloride, cupric sulfate,cupric acetate and cupric subcarbonate as oxidizers.The experimental results indicate that these cupric compounds can all oxidize benzoin into benzil in acetic acid solutions, and cupric nitrate is the best one.Its product has these adventages of fine color and luster,high yield, available raw material and simple and easy operation and it has the prospects of being used widely.

以NaHSO4*H2O催化苯甲酸与甲醇的酯化反应,合成了苯甲酸甲酯.研究结果表明,NaHSO4*H2O具有较高的催化活性.考察了苯甲酸/甲醇摩尔比、催化剂用量及反应时间对酯产率的影响.在优化反应条件[n(苯甲酸)∶n(甲醇)∶n(NaHSO4*H2O)=1∶2∶0.29,回流8h]下,苯甲酸甲酯产率达85.3%.
