摘要
本文报道了甲基紫聚氯乙烯(PVC)膜涂层玻璃电极的研制及应用。该电极是在pH玻璃电极表面涂敷一层对甲基紫敏感的PVC膜构成的。灵敏度高,选择性好,且制作简单使用方便,可直接用于甲基紫的测定。尤其用于动力学分析,与催化光度法比较,操作简单,温度控制容易。用该电极以催化电位法测定几种标准钢样中的锰含量,结果满意。
The methyl violet polyvinyl chloride membrane coated g1ass electrode based on the use of methyl violet material coated on pH glass electrode has been described. It behaves high sensitivity and selectivity and has been used in a new catalytic potentiometric method for determining trace Mn^(2+). The content of Mn^(2+) in standard steel samples is determined. The result obtained is very close to the standard content.
