| Abstract: | A grand-lot fast determination of COD Cr in environmental water samples was conducted using continuous flow analysis,which can be compared with national standard method (potassium bichromate method).Its results have excellent accuracy and reproducibility with a detection limit of 1.3 mg/L and the accuracy of analyzing a standard sample is over 98%,whose variation coefficient is in the range of 0.21%～1.00%;the relative deviation is 0.4%～1.4% between the result of an actual water sampe and that of potassium bichromate method,and the recovery of environmental water samples and industrial wastewater is 93%～101%. |
