Abstract

Background and Objectives: Cyanide is a highly toxic compound which is normally found in numerous industries, such as ELECTROPLATING WASTEWATER. Release of this compound in to the Environment has a lot health hazards. The Purpose of this study is to determine the efficiency of ELECTROCHEMICAL OXIDATION method for Cyanide removal from industrial wastewaters.Materials and Methods: This study conducted in a pilot system experimentally. In this study the effect of pH, voltage and operation time on total cyanide removal from industrial wastewaters by ELECTROCHEMICAL OXIDATION was investigated by applying a Stainless Steel as a Anode and copper as a cathode.Results: The average percentage removal of cyanide was about 88 with SD=2.43. The optimal condition obtained at voltage of 9V and pH=13 and the operation time of 90 minutes. The volume of sludge which formed in this condition was about 20 percent of a one liter pilot reactor.Conclusion: the results statistically confirmed the significant relationship between input and cyanide concentration removal efficiency (p<0.05), and confirmed. The confirmed the relation between cyanide & cyanat oxidation and hydroxyl ions consumption 1:2 (L.Szpyruowicz). therefore the best pH is 12.5-13.5 by considering the need of alkaline environment to remove cyanide.
