Abstract

The adsorption of magnesium (II) and cadmium (II) from industrial phosphoric acid onto 4 samples of clays: crude (a), purified (b), activated (c) and purified-activated (d) bentonite have been studied using a batch adsorber. The parameters that affect the magnesium (II) and cadmium (II) adsorption, such as bentonite amount, temperature, contact time and solution pH have been investigated and optimized conditions determined (bentonite amount 12g/ 100mL of industrial phosphoric acid; temperature 293.15 K; contact time 15 min; pH 1.78±0.1). The loading capacity values were found respectively to be 51.21%and 56.25% for magnesium and cadmium using the purified-activated bentonite.
