【摘要】通过三甲胺修饰超高交联聚苯乙烯树脂NJ-00制备了一种新型树脂(NJ-03),树脂性质表征说明,通过改性季胺基被成功引入,树脂骨架上增加了一定数量的碱性基团。研究了pH、盐浓度对芳香酸类化合物在NJ-03树脂上吸附的影响,并与商品大孔强碱阴离子交换树脂D-201以及大孔弱碱阴离子交换树脂D-301进行对比,探讨了pH和盐浓度影响吸附的机理。更多还原

【Abstract】 Hypercrosslinked polymer(NJ-00) was chemically modified with trimethylamine,and a bifunctional polymer(NJ-03) was achieved.The experimental results show that amino groups were successively added.The Effect of pH and salt on adsorption of aromatic acids by this functional polymeric resin was studied,a comparision of the adsorption behavior under different pH and salt concentration between NJ-03 and commercially macroporous strongly basic anion exchanger resin D-201 and macroporous weakly basic anion exchanger resin D-301 was also made,and the mechanism was discussed.更多还原
