摘　　要：氯离子是高氯废水COD测定中主要干扰物之一。如何消除氯离子的干扰,提高COD测定的准确度,同时减轻二次污染,是广大环境监测者非常关注的问题。文章对消除氯离子干扰方法的研究进行了简要综述,指出了各方法的优缺点及适用范围,以供高氯废水COD测定时参考。Chloride was one of the main disturbing substances on determination of COD in high chloride wastewater. How to avoid the disturbance of chloride and improve the accuracy and reduce secondary pollution was a problem deserving attention from large environmental monitoring workers. In this article, the research in ways of avoiding the disturbance of chloride was briefly summarized, and the merits and demerits, as well as the scope of application of the methods were pointed out. Then a reference for determination of COD in high dhloride wastewater was provided.
