Since the chloride ions interferes with the measurement results of high chloride-containing wastewater, the influence of chloride ions must be eliminated during COD determination process. The methods for eliminating the influence of chloride ions were compared in terms of the determination principles, the elimination effects, the application scopes and so on, and it was thought that appropriate methods should be used for water samples having different chloride ion concentrations and COD.
