Retention of lead from an aqueous solution by use of
The adsorptive properties of bentonite which was made homoionic by exchangeable mono di and trivalent cations Na Li K Ca 2 Mg 2 Al 3 and Fe 3 in leadrich aqueous environment have been results show an increase in the final pH values of the recuperated suspension after exchange of homoionic bentonites with lead aqueous solution prepared at pH 5
