摘要
钢中的硼含量非常低,是钢铁化学分析的一个难点,下面介绍的这种方法是利用在酸性介质中,硼酸与氟离子作用生成氟硼络离子,与次甲基兰形成1∶1蓝色缔合物,可被1.2-二氯乙烷定量萃取。
It is too difficulty to determinate low content boron in the steel, the introducing method is that boric acid and fluorine ion can be maked BF4 , it can create 1：1 compound with hypo - methyl blue,the compound can be extraction using 1.2 - twain chlorine ethane.
