| Abstract: | The content of sodium chloride in sodium carbonate was determined by automatic potentiometric titration using a AgNO3 standard solution as a titrant. The detection limit was 0.13 mg/L. The recovery was 99.7%~100.3% with 0.17%~2.0% RSD(n=5). The proposed method was simple and quick, and could be suitable for rapid analysis of large quantities of samples with high accuracy and precision. |
