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。
The classic aluminum reduction - high-speed ferric sulfate titration method, replaced by sulfuric acid - hydrochloric acid medium, diantipyryl methane and titanium yellow soluble complexes were measured at a wavelength of 420nm at the absorbance, to determine the titanium in titanium the amount. The method is simple, fast and accurate and reliable.
