摘要
以XS-LP为催化剂,探讨了改进的无银催化HACH法测定污水中COD的系列条件实验。结果表明:在药剂A,B的投配比为1∶2,投加总量为12 g/L的条件下,其准确度、精密度与国标法有较好的可比性,分别小于10%和3%;对实际废水的测量结果与国标回流法的相关系数分别高达0.9951和0.9874,可满足一般环境检测技术规范要求。
The content of COD in wastewater was determined by using the method of amended HACH which without silver but with XS-LP as catalyst. The results showed that this method was comparable to the standard method used in China in terms of accuracy and precision, were less than 10% and 3% separately, at ratio of A and B was 1：2, gross was 12 g/L. For wastewater in nature, the linear correlation coefficient with standard method is about 0. 9951 and 0. 9874, accord with the requirement of the monitoring skill standard.
