title: [Kinetics study on reaction of chlorine dioxide and thiocyanide in water].
abstract: OBJECTIVE
  To study the kinetics rule of chlorine dioxide oxidize thiocyanide as the experimental objective.
  
  
  METHODS
  Ultraviolet spectrophotometry was used to detect the concentration of chlorine dioxide and thocyanide which were changed with the time. According to initial rate method to determine the reaction order and rate equation, calculated Constant Rate, the activation energy, the half-life and other parameters.
  
  
  RESULTS
  The reaction of chlorine dioxide oxidize thiocyanide was zero-order reaction both for chlorine and thiocyanide, order of overtall reaction was zero, too. At 293.15 K, k = 3.65 x 10(-6) mol/(L x s). E = 2.5 kJ/mol.
  
  
  CONCLUSIONS
  Its activation energy was very little, reaction was fast. In general condition it could occour,while thiocyanide remained merely. It provided a new method for industry to deal with the waster contained thiocyanide.
