Abstract
The cation exchange separation of lead from associated elements on Dowex 50W-X8, was carried out in mixed solvent systems. Elution behaviour was studied with 0.75 M HCl in the presence of various concentrations of solvents such as methanol, ethanol, 2-propanol, acetone, 1, 4 dioxane and tetrahydrofuran. Tetrahydrofuran, 1, 4 dioxane and acetone were effective in the presence of hydrochloric acid. At low concentrations of methanol, ethanol and 2-propanol in hydrochloric acid were useful for the separation of ions from lead. Lead was separated from binary and as well as multicomponent mixtures. The method was extended to the separation of lead from lead base alloys.
