聚酯纤维中二氧化钛含量的分析测定

Determination of titanium dioxide content in polyester fiber

介绍了聚酯纤维中二氧化钛(TiO2)含量的测定方法。溶液中硫酸浓度为2 mol/L,质量分数为3% 的过氧化氢加入量为5 mL,采用浓硫酸溶解加热处理,可快速测定聚酯纤维试样中TiO2的含量。试样测定的相对误差为1.92%。

The determination of titanium dioxide content in polyester fiber was introduced. Titanium dioxide content can be measured quickly through dissolving and beating concentrated sulfuric acid. The standard deviation of the measurement was 1.92% when the sulfuric acid concentration was 2 mol/L and the addition of 3% hydrogen peroxide by mass fraction was 5 mL.
