Removal of lead (II) from synthetic solution by adsorption onto coal mining waste material

Abstract

Coal/metals, mining, ore processing, and smelting activities pollute water resources with heavy metals all over the world. In this paper, mine waste materials (sandstone) obtained from mine site was used for the uptake of Lead (Pb) ions from the synthetic solution. Laboratory analysis was conceded to study the effects of adsorption parameter like, pH, temperature, contact time, adsorbents dose, on Lead adsorption; the obtained experimental data showed that adsorption of waste materials had a higher adsorption capacity at shorter contact time at pH 5.0. The present investigation demonstrates the sandstone as mine waste material can be effectively utilized for the treatment of Lead (II) laden synthetic solutions by adsorption process. © RASĀYAN.
