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+.
