研究了二价锌离子在磷酸双（2-乙基己基酯）（D2EHPA）浸渍大分子树脂水溶液中的平衡分布。浸渍吸附剂对Zn（II）的吸附机理与溶剂萃取的吸附机理不同，用简单离子交换反应表示，用简单离子交换反应表示，平衡常数为0.036 kg吸附剂/dm 3
Studies have been conducted on the equilibrium distribution of divalent zinc ion between aqueous solution and macromolecular resin impregnated with phosphoric acid bis(2-ethylhexyl ester) (D2EHPA). The mechanism of Zn(II) sorption on the impregnated sorbent is different from that for the solvent extraction, being expressed by a simple ion-exchange reaction, being expressed by a simple ion-exchange reaction, with the equilibrium constant of 0.036 kg of sorbent/dm 3
