钢铁中微量硼的测定,ASTM用硼酸甲酯蒸馏姜黄素比色法;JIS用硼酸甲酯蒸馏法、离子交换法或汞阴极电解法分离后用胭脂红显色;我国标准YB推荐用硼酸甲酯蒸馏姜黄素比色法。这些方法需要一套昂贵的石英蒸姻装置和无硼玻璃容器。
Steel Determination of trace boron, ASTM boric acid methyl ester distillation curcumin colorimetric; JIS using methyl borate distillation, ion exchange or mercury cathodic electrolysis method with carmine color; standard YB recommended boric acid Ester distillation curcumin colorimetric method. These methods require an expensive quartz distillation apparatus and a boron-free glass container.
