Abstract

Mining industries contribute enormously to water pollution through discharge of effluents contaminated with metals. Metals-polluted water is a threat to aquatic and human lives as well as the general ecosystem. Numerous conventional treatment methods are available for the removal of metals from mine water, but majority of them are costly, inefficient for trace metal concentration, and generate voluminous secondary sludge. Therefore, there is need for alternative low-cost novel technologies capable of reducing metal concentration in water to acceptable levels. Adsorption technology is increasingly receiving preference because it is simple in design, requires low initial cost, easy to operate, can remove contaminants in trace levels and the possibility to develop and employ wide variety of adsorbents. This study, therefore, explored the removal of manganese [Mn (II)] from aqueous solution using a …
