摘要
硼酰化钴中硼的测定采用 EDTA作为钴的络合掩蔽剂 ,消除了钴对测定硼的影响。同时改用溴甲酚绿 -甲基红 -酚酞三元混合指示剂作为测定硼的指示剂 ,使滴定终点灵敏、准确。建立了一种测定硼酰化钴中硼含量的简便、快速的分析方法。
It is described in this paper that the acid base titration method is applied to the determination of boron in cobalt boron complex. The interference of cobalt is eliminated by masking with EDTA. A mixed indicator composing of bromocresol green, methyl red and phenalphthalein is used as indicator in the titration, to give a sensitive and sharp end point. The method is proved to be accurate, rapid and convenient.
