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 K-F 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.

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：
Graphene sheets (GS)@ manganic manganous oxide (Mn3O4) nanocomposites were prepared via a simple solvothermal process. GS@Mn3O4/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 (GS@Mn3O4) 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 vertical bar GS@Mn3O4/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 x 10 (-6) to 1.3 x 10(-3) M (R = 0.9985) with a detection limit of 8.0 x 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.

摘要：
A novel p-acetaminophen resin (named as GQ-1) was synthesized with chloromethylated polystyrene and p-acetaminophen. It can be used without any wetting process. The objective of this work was to study the adsorption performances for vanillin onto GQ-1 with two kinds of the hydrogen bond site of acetamino group and hydroxyl group. The results showed that the adsorption property of vanillin onto GQ-1 was superior to XAD-4, H103, NDA150, and NDA88. The adsorption capacity of vanillin onto GQ-1 is not greatly discrepant until the solution pH is higher than 5.31. The saturated adsorption quantity of vanillin was up to 141.32 mg/mL (wet resin) according to the dynamic adsorption and desorption experiments at 293 K. The resin could be regenerated by 7 BV ethanol.

摘要：
A novel hyper-cross-linked polymeric adsorbent modified with acetylaniline as the cross-linked bridge (denoted GQ-02) was synthesized for the enhanced removal of bisphenol A (BPA) from aqueous solution. Its chemical structure and pore structure were characterized by infrared spectroscopy and surface area analysis. Results showed that the adsorption capacity of BPA onto GQ-02 was larger than that of the commercial resins NDA-150, H103, NDA-88, NDA-99, and XAD-4 due to the cross-linked bridge of acetylaniline uploaded on GQ-02 resin. The solution pH had no significant effect on the adsorption capacity until it was higher than 6.39. The adsorption rate of GQ-02 was greater than that of H103 because of the longer cross-linked bridge between two benzene rings. The adsorption isotherms could be correlated to the Langmuir equation. More favorable adsorption of BPA onto GQ-02 than H103 was further demonstrated by thermodynamic analysis. Nearly 100% regeneration efficiency for GQ-02 was achieved by 80% ethanol and 0.5 mol/L NaOH.
