Metal ion exchange by natural and modified zeolites
TL;DR: In this article, the lead and cadmium removal from wastewaters by natural and pretreatment zeolites was examined by using a batch-type method, and the results demonstrated that the natural zeolite contained a complement of exchangeable Na, K and Ca ions but exposing them to 2 M NaCl solution at 22 and 70°C, respectively, converted them to a near homoionic state in Na-form.
