目前,硅酸盐样品中硼的测定多采用酸碱滴定法或姜黄素比色法,由于这些方法受许多常见元素和成份的干扰,往往需要经预先沉淀分离或蒸馏分离,故操作繁琐,时间冗长。Robelt L.Kochen 曾报导用 BF~-选择电极测定硼硅玻璃中的硼,但是需经离子交换分离处理,操作亦较繁琐。本文研究了普通硅酸盐样品的分解及硼的测定条件,用
At present, the determination of boron in silicate samples mostly adopts acid-base titration or curcumin colorimetric method. Because these methods are disturbed by many common elements and components, they often need to be pre-precipitated or separated by distillation, so the operation is cumbersome, time lengthy. Robelt L. Kochen has reported the determination of boron in borosilicate glass using a BF ~ - selective electrode, but requires ion exchange separation to be more cumbersome. This article studies the decomposition of ordinary silicate samples and determination of boron conditions, with
