A by product from steel industry mainly known as blast furnace slag is a waste product which was tested for the removal of As(III), from ground water. Steel slag is a commercial waste material mainly consisting of SiO2, Al2O3 and CaO, the former two chemicals being major components of zeolites and the latter a major component of Hydroxyapatite (HAP). Arsenic is highly toxic, mobile and predominant species present in groundwater. Batch experiment was performed to determine the feasibility of steel industry waste as an adsorbent for treatment of heavy metal present in ground water at a wide range of pH 3-12. The results suggest that steel slag is a suitable candidate for As(V) remediation and economically viable to apply in the areas where cost of a purification process is high.
