有机硼化合物在分解后通常转化为硼酸,需以甘露糖醇使其形成络合物,再用标准氢氧化钠溶液滴定。氧瓶分解法分解有机硼化合物,常需在样品燃烧前于样品内加入蔗糖、氢氧化钾或EDTA二钠盐。Gadson等在含硼无机溶液中加入少量10％氢氟酸,10分钟内形成BF_4~-,然后用流动载体氟硼酸根离子选择电极直接电位法进行测定。由此,我国刘成梁等首次提出氟硼酸根离子选择电极标准添加法,应用于有机硼元素微量分析。
Organoboron compounds are usually converted to boric acid after decomposition, requiring mannitol to form complexes and titration with standard sodium hydroxide solution. Oxygen vial decomposition decomposition of organic boron compounds, often in the sample before combustion in the sample by adding sucrose, potassium hydroxide or EDTA disodium salt. Gadson and other boron-containing inorganic solution by adding a small amount of 10% hydrofluoric acid, BF4 ~ - within 10 minutes to form, and then use a mobile substrate fluoroborate ion selective electrode direct potential method was measured. As a result, Liu Chengliang et al. First proposed the standard addition method of fluoroborate ion selective electrode and applied it to the trace analysis of organoboron.
