Acid mine drainage (AMD) is one of the most significant environmental problem resulting from the oxidation of pyrite in presence of water, air and microorganisms, providing an acidic solution that contains heavy metal ions. Copper ions are an essential part of AMD, which is characteristic by low value of pH. This fact has a significant effect on research of the sorption properties of Cu(II). Aim of...
The sorption of three divalent metal ions — copper, nickel and lead — from aqueous solution onto peat in single component systems has been studied and the equilibrium isotherms determined. The experimental data have been analysed using the Langmuir, Freundlich, Redlich-Peterson, Toth, Temkin, Dubinin-Radushkevich and Sips isotherm models. In order to determine the best fit isotherm for each system,...
