钛及钛合金中微量硼的测定,大多采用蒸馏分离一姜黄素比色法和次甲基蓝比色法等,这些方法操作手续比较繁杂,特别是次甲基蓝法,需在氢氟酸介质中萃取,操作很为不便.随着硝酸根液膜电极的出现,提出了这类电极对氟硼酸根产生响应的可能性(NO_(3)~(-)与BF_(4)~(-)的行为有许多相似之处)随着氟硼酸根电极的研制成功,国内外已经应用氟硼酸根电极测定钢、硅、氧化铝—碳化硼及水中的硼.本文针对钛及钛合金中硼的测定,作了条件试验,方法简便,结果令人满意.
Titanium and titanium in the determination of trace boron, mostly by distillation separation of a curcumin colorimetric method and methionine colorimetric method, the procedures for these methods is more complicated, especially methylene blue method, the need to hydrofluoric acid (NO_ (3) ~ (-)) and BF_ (4) ~ (-) have been proposed in this paper.With the appearance of nitrate liquid membrane electrode, ) Have many similarities with the behavior of fluorite electrode.With the successful development of fluoroborate electrode, the determination of boron in steel, silicon, alumina-boron carbide and water by fluoroborate electrode has been carried out at home and abroad.In this paper, Of the test, made a conditional test, the method is simple, the results are satisfactory.
