摘要
研制了一种能对ＢＦ－４响应的ＣＰＣ－ＢＦ－４－ＰＶＣ涂膜石墨电极。提出了一个快速测定硼的零电流示波电位滴定法。以氯化十六烷基吡啶（ＣＰＣ）为滴定剂，用涂膜石墨电极为指示电极，甘汞电极为参比电极。利用阴极射线示波器荧光屏上荧光点的突然位移来指示ＣＰＣ滴定硼的终点，具有灵敏、准确、快速等特点。用该法测定陶瓷中的硼，结果良好。
In this paper,a CPC-BF - 4-PVC smear membrane graphite electrodes was made.A simple and rapid method of zero current oscillo potentiometric titration of boron is put forward.Cetylpyridinium chloride(CPC) solution is used as titrant.Smear membrane graphite electrode and calomel electrode are used as indicator electrode and reference electrode.The end point of titration of boron by CPC is indicated by the sudden movement of a fluorescent spot on the screen of the cathode ray oscillograph.The new method is sensitive,precise and quick.The results of determining boron in ceramic with the present method are in accord with the reference values.
