| 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。

| Abstract: | 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 sen-sitive and sharp end point. The method is proved to be accurate, rapid and convenient. |
