%X The chelate resins of dicarboxylic acid dihydrazides-formaldehyde were synthesized by polycondensation of dicarboxylic acid dihydrazides with formaldehyde. The collecting ability for Zn2+ was investigated by batch tests. The collecting efficiency of these three resins decreased in the order of succinic acid dihydrazides-formaldehyde resin>malonic acid dihydrazides-formaldehyde resin>oxalic acid dihydrazides-formaldehyde resin. The influences of pH value, capturing time and temperature were investigated. It is found that the collecting efficiency is dependent on pH value, and high temperature is unfavorable to collecting Zn2+. The resins reach the highest capacity of Zn2+ capture after 3 h of adsorption.
