Abstract

Backgrounds and Objectives: Industrial wastewater included the heavy metal is one of the important sources of environmental pollution. HEXAVALENT CHROMIUM and DIVALENT NICKEL are founded in plating wastewater which is harmful for human health and environment. Therefore, the purpose of this research is investigation of photocatalytic removal of HEXAVALENT CHROMIUM and DIVALENT NICKEL from AQUEOUS SOLUTION using UV/TiO2 process in a batch system.Materials and Methods: At first, reactor was designed. Then, optimum dosage of TiO2 was obtained equal to 1 g/L, with variation TiO2 dosage at constant pH and initial concentrations of HEXAVALENT CHROMIUM and DIVALENT NICKEL. The effect of pH, contact time and initial concentration of HEXAVALENT CHROMIUM was studied at the constant amount of TiO2 (1gr/L).Results: The result showed that photocatalytic removal efficiency increased with increasing reaction time and TiO2 dosage. In addition, it was found that removal efficiency of HEXAVALENT CHROMIUM was decreased by increasing initial chromium concentration and pH. But, photocatalytic removal efficiency of nickel ion was increased and decreased by increasing of pH and initial nickel concentration, respectively.Conclusion: The results showed that UV/TiO2 was an effective method in removal of HEXAVALENT CHROMIUM and DIVALENT NICKEL from AQUEOUS SOLUTIONs.
