摘要
研究了钛、铁与钛铁试剂的显色反应。该分析方法的最大优点是可在同一溶液中用光度法连续测定样品中的钛和铁含量。配合物最大吸收波长分别为 41 0nm和 5 65nm ,二氧化钛含量在 0～ 2 0 0 μg/5 0ml,三氧化二铁含量在 0～ 3 0 0 μg/5 0ml范围内符合比尔定律。方法用于测定硅酸盐样品中钛和铁 。
The development reaction of Ti,Fe with reagent is researched,The most advantage of the method is that the content of Ti and Fe can be measured continuously with luminosity in the same solution.The most absorbing wavelength of the mixed material are 410 nm and 565nm respectively.It accords with the law when the content ranges of TiO\-2 are between 0～200μg /50m and that of Fe\-2O\-3 between 0～300μg/5oml. With the method the measurement results of Ti and Fe in silicate samples are satisfactory.
