中文摘要:

      结合标准加入法，对高浓硫酸盐样品中低浓度氯离子测定的经典汞量法进行了改进。实验证实，改进后的汞量法能更好地用于高浓硫酸盐样品中低浓度的氯离子定量测定，具有终点颜色突变明显．测定结果准确可靠，实验操作十分简便，有利于节约实验时间和成本等优点。

英文摘要:

      Classic mercurimetry for determination of chlorine ion of low concentration in high concentrated sulfate sample has been improved with combination of standard addition method in the paper. The experiments have been confirmed that the improved mercurimetry can be better used to quantitatively determine the chloride ion of low concentration in high concentrated sulfate samples. The color mutation at end point of the titration is very obvious, with many advantages, such as accurate and reliable results, simple opera- tion, low experiment cost and time-saving,etc.
