| 摘 要： | 对CODCr值较低，但氯离子浓度很高的水样中CODCr的测定方法进行了初步研究，比较了稀释法、硝酸银法、硫酸汞加入法各自的优缺点。结果表明，用硝酸银法测定悬浮颗粒物较少的水样中CODCr，既可去除水样中Cl^-的干扰，又可真实地测定CODCr值，同时也不会带来二次污染。

| Abstract: | In this paper, the effect of high concentration of Cl\+- in the aqueous solution was studied. The methods were compared, i.e., dilution, addition of silver nitrate or addition of hydrargyrum sulfate. The results show that the influence of chlorine can be greatly eliminated by addition of the hydrargyrum sulfate? |
