| Abstract: | Derivative spectrophotometric method was introduced to detect pulping effluent COD rapidly in the paper. The linear relationship between derivative spectrophotometric signal at 251nm and COD detected by traditional method was established. The COD value of test samples will be calculated according to the relationship and the derivative spectrophotometric signal at 251nm. The procedures of determination were simplified and the error caused by human factors was reduced. The method is characterized by no need of chemicals, low cost and no pollution. In addition, derivative spectrophotometric method as a clean alternative method for the determination of pulping effluent COD has higher precision and higher accuracy within 400mg/L COD value. |
