Abstract
In this study, fly ash, china clay and red mud were investigated for their potential as adsorbents to remove heavy metals such as lead, cadmium and chromium from wastewater of known concentrations. Therefore, this study shows that the low-cost adsorbent China clay was used to remove 89%, 86% and 90% of chromium, lead and cadmium, respectively. Red mud removes 91%, 94% and 89% of chromium, lead and cadmium, respectively. Fly ash was used to remove 84%, 89%, and 83% of chromium, lead, and cadmium, respectively, from the effluent of solutions with an initial metal ion concentration of 100 ppm. Batch adsorption studies have shown that the adsorbent has significant adsorption capacity for chromium, lead, and cadmium in aqueous solutions. The adsorption was found to increase with increasing contact time.
