环境中邻苯二甲酸酯类化合物降解技术研究进展

Progress of Degradation Techniques of Environmental Phthalic Acid Esters

邻苯二甲酸酯类(PAEs)是重要的工业原材料,用于多种合成工艺中,但其能产生类似雌激素样作用,对人类健康和环境造成严重危害,因而研究PAEs降解技术,控制其在环境中的污染浓度具有非常重要的意义。该文综述了近年来PAEs降解技术的进展情况,详细讨论和比较了生物降解、物理吸附、高级氧化技术的优缺点,并指出光催化氧化技术是今后邻苯二甲酸酯降解的发展趋势。

Phthalic acid esters （PAEs） were an important industrial material and used in many synthesis technology. But PAEs was postulated to produce endocrine-disrupting effects when people were constantly exposed to it, so it was drastically important to study the degradation technology of PAEs. This paper reviewed the progress in the PAEs degradation field in recent years, the merit and demerit of biodegradation, physisorption and advanced oxidation technology were detailedly discussed and compared and it was indicated that photocatalytic oxidation was the most promising technology of PAEs degradation.
