제목 Oxidation features of cyanide ion by H2O2 and the effect of homogeneous catalyst
초록 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 Cu2+ or Cd2+ as catalysts resulted in increasing reaction rates. In alkaline conditions, the catalytic effects of Cu2+ or Cd2+ were accelerated and Cu2+ was found to be a more effective catalyst than Cd2+.
