Abstract

Cadmium is amongst the most toxic and hazardous heavy metals found in surface and aqueous effluents from various manufacturing processes. In this study, the potential of Brachystegia eurycoma seed hulls to remove cadmium ions from aqueous solution was investigated. The effects of concentration of adsorbate (10-100mg/l), time of contact (20-100minutes), pH (2-10) and adsorbent dose (1-5g) on the adsorption of cadmium ions was studied. Within the range of variables studied, 98% cadmium ions were removed from aqueous solution at pH of 6, contact time of 40minutes, adsorbent dose of 1g and concentration of adsorbate of 30mg/l. The result indicated that Brachystegia eurycoma seed hulls were suitable for adsorption of cadmium from aqueous solution.
