摘 要：
研究了4-氨基吡啶树脂吸附锌的行为,结果表明在pH=2.63的HAc-NaAc体系中,树脂对锌(Ⅱ)有较好的吸附,其静态饱和吸附容量为58.4mg/g树脂,表观速率常数k298=3.42×10-5s-1,用pH=1-4的不同浓度盐酸洗脱,洗脱率均达100%。

摘 要：
The sorption behavior and mechanism of 4-the structures of aminopyridine resin(4APR)for Zine is investigated.4-APR has a good adsorption ability for Zn(Ⅱ) in theHAc-NaAc medium at pH=2.63.Experimental results show that the statically saturated sorption capacity is 58.4 mg/g.resin. The apparent rate constant is K298=3.42×10-5s-1.Zn(Ⅱ) adsorbed on 4-APR can be eluted by pH=1-4 HCl elution percentage is 100 %.
