The chloride ion to the chemical oxygen demand (COD) analysis of the influence of different analysis method

Abstract

Research shows that chloride ion in the process of chemical oxygen demand (COD) analysis has a huge impact on the results of the analysis, How to improve the accuracy of chemical oxygen demand analysis results in the presence of chlorine ion interference is a difficult problem in current environmental monitoring work, This article introduces the chlorine ion in different analysis method to analysis the influence degree of the chemical oxygen demand (COD).
