Discussion on Chloride Ion Interference and Elimination Strategies inDetermination of Chemical Oxygen Demand

本文旨在探究化学需氧量(COD)测定中氯离子的干扰及消除策略,针对氯离子干扰,提出了添加还原剂和抑制剂两种消除氯离子干扰的策略,并比较了其他消除氯离子干扰的方法。最后,设计了实验并展示了实验结果,验证了添加还原剂和抑制剂消除氯离子干扰的有效性。本研究的结果可为COD测定中氯离子干扰的解决提供参考和借鉴。

This paper aims to explore the interference and elimination strategies of chloride ions in the determination of chemical oxygen demand(COD).Aiming at the interference of chloride ions,this paper proposes two strategies to eliminate the interference of chloride ions by adding reducing agent and inhibitor,and compares other methods for eliminating the interference of chloride ions.Finally,an experiment was designed and the experimental results were presented,which verifi ed the effectiveness of adding reducing agents and inhibitors to eliminate chloride ion interference.The results of this study can provide reference and reference for the solution of chloride ion interference in COD determination.
