摘要
研制了一种结晶紫ＰＶＣ膜涂层玻璃电极。它是在普通ｐＨ玻璃电极表面涂敷一层对结晶紫敏感的ＰＶＣ膜构成的。该电极灵敏度高，选择性好，且制作简单，使用方便。它可直接用于结晶紫的测定，也可用于动力学分析方法中。本文用该电极以动力学法测定了标准钢样中的锰含量，结果满意。
The crystal violet polyvintyl chloride membrane coated glass electrode is studied.It is based on the sue of crystal violet active material coated on pH glass electrode.It shows high sensitivity and selectivity.It has been sued in a new kinetic method for determining Mn in standard steel sample.The result obtained is close to the standard content.
