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%。
The adsorption behavior of zinc on 4-aminopyridine resin was investigated. The results showed that the resin adsorbed zinc (Ⅱ) in the HAc-NaAc system at pH = 2.63 with a static saturated adsorption capacity of 58.4mg / g resin View the rate constant k298 = 3.42 × 10-5s-1, with pH = 1-4 different concentrations of hydrochloric acid elution rate of 100%.
