The Novel Use of Processed Ninivite-Kaolin Mixture Part 2: Cadmium and Lead Removal from Their Effluents

Cadmium and lead effluents had been treated with a (1:1) mixture of low grade ninivite (N) and Kaolin (K). Before use, the mixture is treated only with a 10% brine solution and found to be effective for the removal of 85% Cd ( at a maximum concentration of 200mg/) at a pH of 11.5 and 90% Pb (at a maximum concentration of 1000 mg/) at a pH 7.0. The results were compared using Dowex-50X, as a typical cation exchanger and activated carbon (charcoal), as an ideal adsorbent and found to be satisfactory
