摘要

氯球和对甲基酚发生Friedel-Crafts反应制备对甲基酚修饰的超高交联树脂(简记为GQ-03)

研究 GQ-03树脂对4-硝基苯胺(PNA)的吸附性能。实验结果表明:GQ-03树脂的比表面积高达1154. 45m

树脂孔径分布在微孔(0〜2nm)、中孔(2〜50nm)区;GQ-03树脂对PNA的吸附性能优于商业NDA-88、NDA-99、 NDA-150、XAD-4和H103树脂;当溶液pH值在3. 1〜8. 0之间

GQ-03树脂对PNA的吸附量最大;GQ-03树脂对PNA的吸附量随温度的升高而降低

树脂对PNA的吸附等温线符合Freundlich模型;GQ-03树脂对 PNA的饱和吸附量为154. 41mg/mL

解吸率为 98. 82%。

Abstract

The objective of this work was to study the adsorption performances for p-nitroaniline onto the p-cresol hyper-cross-linked resin (denoted GQ-03). GQ-03 resin was synthesized with chloromethylated polystyrene and p-cresol by Friedel-Crafts reaction. Dichloroethane was used as solvent. The results showed that the BET surface area of GQ-03 resin was up to 1154. 45m

/g. Only microporous and mesoporous were present in GQ-03 resin and there were no macropores in the polymeric adsorbent. The adsorption property of p-nitroaniline onto the GQ-03 resin was superior to commercial NDA- 88 resin

NDA-99 resin

NDA-150 resin

XAD-4 resin and H103 resin. The maximum adsorption capacity of GQ-03 resin emerged the pH range of 3. 1-8. 0. The adsorption capacity of p-nitroaniline onto the GQ-03 resin increased with the increase of the temperature. The adsorption isotherms could be correlated to the Freundlich model. The saturated adsorption quantity of p-nitroaniline was up to 154. 41mg • mL

. The resin could be desorbed with 8. 8BV 80% ethanol and lmol/L hydrochloric acid. The desorption rate was 98. 82%.
