Abstract

The use of Cr(III) heavy metals in the leather industry is quite common and therefore the leather industry has high concentrations of Cr(III) heavy metals in wastewater. In this study, it was aimed to remove the chromium ions from the wastewater of leather industry by means of the amino oxime ligand, which is selective for heavy metal ions and allows reuse of the complex formation. These studies were supported by the kinetic experiments. Pseudo-first and second order kinetics was used for correlation of complex formation data and rate constants were determined. In almost all conditions, experimental data were found to be better suited to second-order complex formation kinetics. The highest rate constants were found to be 0.432 min(-1) and 0.0312 (mg g(-1))(-1) min(-1) for the first and second order kinetics, respectively, at the highest concentration of amino oxime tested (3 g L-1).
