Abstract
Batch kinetic tests were conducted to determine the effects of experimental conditions and catalysts on cyanide degradation. Cyanide degradation by hydrogen peroxide was found to follow first-order kinetics. Reaction rates increased with increasing pH and decreasing temperature. The activation energy for cyanide degradation by hydrogen peroxide was found to be -13.81 kJ/mol. The addition of Cu 2+ or Cd 2+ as catalysts resulted in increasing reaction rates. In alkaline conditions, the catalytic effects of Cu 2+ or Cd 2+ were accelerated and Cu 2+ was found to be a more effective catalyst than Cd 2+. The practical relevance of the laboratory oxidation method of cyanide was demonstrated for actual industrial wastewater.
