有机化合物中硼的微量分析一般采用氧瓶分解,便有机硼转化成硼酸,然后在甘露醇存在下,用氢氧化钠标准液进行滴定。这种方法有时对含有B—N,C—B键的化合物难分解完全,有时对金属元素中硼的测定,由于有颜色的干扰,在进行氢氧化钠滴定时,致使终点不易看清,对测定结果带来一定影响。1969年后,开始出现离子选择电极与有机元素微量分析这两门学科的结合,它在某
Micro-analysis of boron in organic compounds is generally carried out using oxygen bottle decomposition, organic boron is converted to boric acid, and then titrated with sodium hydroxide standard solution in the presence of mannitol. This method is sometimes difficult to decompose the compounds containing B-N and C-B bonds completely. In some cases, the determination of boron in metal elements is not easy to see when the sodium hydroxide titration is performed due to the color interference. Measurement results have a certain impact. After 1969, the combination of the two disciplines of ion-selective electrodes and trace elements in organic elements began to appear,
