摘要
试样以混合溶剂溶融，盐酸浸取，定容移取分液后，在1．2～3．0mol／L的盐酸介质溶液中，用抗坏血酸还原掩蔽锰和铁等干扰元素，二安替吡啉甲烷与钛生成黄色络合物，于波长420nm处测量吸光度，计算TiO2的含量。
After the sample was melted with mixed solvent, leached with hydrochloric acid and constant- volumed, with some taken, in 1.2 - 3.0mol/L solution of hydrochloric acid medium, ascorbic acid was used to reduce-mask the disturbing elements like manganese and iron, and diantipyryl methane and titanium made yellow complex. Absorbency was measured at the place of 420nm in wavelength, by which the content of TiO2 was calculated.
