摘要
在硫酸-盐酸的酸性介质中,四价钛与二安替比林甲烷生成黄色可溶性络合物,其黄色络合物色泽的强度与钛含量成一定比例关系,借此可用光度法测定稀土硅镁铁合金中钛含量。
In acid medium of sulphuric acid and hydrochloric acid, the Ti4 + and diantipyrylmethane will form yellow color dissoluble complex. The color and luster of yellow complex has a definite proportional relationship with Ti content, so that Ti content in Si - Mg- Fe alloy can be determined with photometric method.
