| Abstract: | This paper compared the central control analysis methods of mercurimetric titration and argentometry for determination of sodium chloride content in caustic soda production,discussed their advantages and disadvantages.The results show that the mercurimetcic titration method and argentometry method compiled and improved by the anthor are cost-effective(about 0.1 to 0.18 million yuan per year),sensitivity high,equivalent point acute for color transformation and more suitable for central control analysis. |
