Fundamental aspects of lead extraction and stripping by a liquid ion exchange reagent

LIX 34 liquid ion exchange reagent was introduced commercially by General Mills in 1976. The fundamental aspects of lead extraction and stripping using LIX 34 as the organic extractant in acetic solution has been studied here. Equilibrium isotherms for extraction and stripping, isothermal pH effects, temperature effect, loading capacity and the rate of extraction and stripping on the system Pb²⁺-HAc-LIX 34—Kermac 470B are reported.
