H2O2光度法测定粘土耐火材料中二氧化钛

样品用碱性熔剂熔融，酸化定容，在硫酸介质中，钛与过氧化氢生成黄色的H2[TiO2（SO4）2]络合物，可进行钛的分光光度法分析，测定结果与标准值基本一致。

The sample is melted using alkaline agent and defined volumetrically by acid. In sulfuric acid media, titanium and hydrogen peroxide generate into yellow complex of H2 [ TiO2 （ SO4 ） 2 ]. Titanium can be deter- mined by spectrophotometry with determination result basically conforming with standard values.
