摘要
采用硫酸汞掩蔽法和氯气校正法分别测定采输废水中高氯废水COD,结果表明:2种方法针对氯离子浓度小于20 g/L的采输废水水样进行分析时准确度高,方法可行;对于氯离子浓度大于20 g/L低COD的采输废水水样进行分析时,氯气校正法准确度高,较硫酸汞掩蔽法具有明显优势。
The COD in wastewater containing high chloride was determined by using mercury sulfate masking method and chlorine emendation method. The results showed that two kinds of method was precise and feasible when the chloride ion concentration less than 20 g/U For the chloride ion concentration more than 20 g/L and low COD, the chlorine emendation method with high accuracy had obvious advantages.
