摘要: 基于过氧化氢的光分解反应,探索了一种新的分析工业金红石型钛白粉颜料紫外屏蔽性能的方法。 在主波长为365 nm的紫外光源下,钛白粉颜料水悬浮体系中,通过氧气生成动力学可以有效地反映不同钛白粉紫外屏蔽性能差异。 该方法具有简单快捷、重现性好等优点。

Abstract: The UV shielding property of TiO2 pigments was investigated via the photodecomposition of hydrogen peroxide in aqueous medium. Based on the oxygen evolution kinetics, a series of pigments can show different UV shielding properties directly and effectively under UV irradiation(mainly 365 nm). This method is simple, fast and reproducible, and it may have potential applications in industrial production and practical useage.

Key words: TiO2 pigment, hydrogen peroxide, kinetics, UV shielding
