A Lalmi, KE Bouhidel, B Sahraoui, C el Houda Anfif - Hydrometallurgy, 2018 - Elsevier
This research aimed at selective removal of Pb++ from polluted waters by cation exchange
resin in Ca++ form, and regeneration with a novel process using Ca (NO 3) 2. This process
brings together remarkable advantages: selectivity, sustainability, economy, safety, simplicity
and applicability. The main findings of this study were the selective and efficient removal of
Pb++ by a conventional cation exchange resin Purolite C100E, the utilization of Ca (NO 3) 2
for regeneration, and the purification treatment of regeneration effluents for Ca (NO 3) 2 total …
