电位滴定仪测定Cl^-含量实验参数设定的讨论

Discussion of Experimental Parameters Set about Cl^- Content Measurement by Potentiometric Titrator

以银电极为响应电极,217双盐桥甘汞电极为参比电极,用硝酸银溶液滴定盐样溶液中的氯离子,参考样品溶液的浓度范围,终点突跃量等因素影响,合理设置仪器参数,从而完成样品的自动分析。

Using the silver electrode as response electrode and the Type 217 calomel electrode for two salt bridges as the reference electrode,chloride ions in the salt solution was titrated by silver nitrate solution. Considering concentration range of sample solution,the end jump value and other factors,a reasonable set of instrument parameters was used to complete the automatic analysis of the sample.
