Abstract:

This study is focused on the feasibility that utilized the sealed spectrophotometer to measure the CODCr of bleaching effluent. The results of t-test demonstrates that it can be used for the measurement of CODCr the same as the method described in standard method,and the Pearson coefficient is 0.999 5.

Key words: spectrophotometer, bleaching effluent, sealed tube method, COD

摘要:

探讨了密闭式分光光度法测定漂白废水的可行性,t—检验的结果表明,该方法与目前采用的CODCr标准方法测定结果无显著差异,泊松相关系数为 0.9995。
