Abstract
Abstract
The granulated slag of a steel plant was analysed for major and minor components. It was found to contain iron and manganese (along with some other metals in traces) in a state suitable for causing electrochemical reduction of a number of extraneously added metal ions. The extent of reduction of the metal ions was found to be in the order of their standard electrode potential values. By controlling parameters such as weight of slag used, pH, concentration and flow rate, a scheme for the selective removal of toxic metal ions such as Hg(II), Pb(II), cu(II) and Zn(II) was carried out. The method showed promise of application in the removal of toxic metal ions from solutions and effluents.
