二安替比林甲烷光度法快速分析钛铁及钛芯线中钛

Rapid analysis of titanium content in ferrotitanium by diantipy rylmethane photometric method

将经典的铝还原—硫酸高铁滴定法,改为在硫酸—盐酸介质中,二安替比林甲烷与钛生成黄色可溶性络合物,在波长420nm处测量吸光度,借此进行测定钛铁中钛量。该法操作简便、快速、结果准确可靠。

This article changed the classical method of Al reducing Fe2 （SO4）3 titration to diantipyrylmethane photometric method. Absorption spectrum of this complex is measured in 420nm wavelength, so titanium content in ferrotitanium will be determined. This method is easy and fast, satisfactory results are obtained.
