| Abstract: | This paper carries on the quantitative analysis on the chloride content of carboxymethyl starch sodium using the spectrophotometry and studies the influence of the measuring wavelength and the reaction time on the absorption value. When the detecting wavelength is 342nm and the reaction time is 40min, the chloride content in carboxymethyl starch sodium is detected quantificationally, and it＇s compared with the national standard method. |
