| Abstract: | 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. |
