Abstract:
Dichromate method, the determination of the COD(Chemical Oxygen Demand)takes long t ime and large space to get the satistory result.To solve these problems, COD determination by cataly tic rapid method is used.This method can shorten the time of determination, lower energy consumption and take smaller space.The precisio n and accuracy of the method can meet the quality control requirement
