邻苯二甲酸酯降解技术研究进展

A Review of Degradation of Phthalate Esters

邻苯二甲酸酯(Phthalate Esters,PAEs)是一类广泛使用的化学品,主要用于聚氯乙烯的增塑剂,PAEs具有雌激素效应,其降解处理十分重要。文章回顾了邻苯二甲酸酯生物降解法、吸附法和高级氧化法的有关研究,着重讨论了PAEs的化学氧化、催化氧化、光化学氧化、光化学催化氧化技术等高级氧化技术。其中光化学催化氧化技术作为一种要求的反应条件温和、降解效果理想的绿色环保技术,值得进一步研究开发。最后展望了PAEs降解技术的研究趋势。

The phthalate esters represent a class of chemicals largely used, mainly as plasticizers for polyvinyl chloride in a wide range of domestic and industrial applications. This paper reflected the related researches of degradation of PAEs by means of biological methods, adsorption, and enhanced oxidation technologies. Enhanced oxidation technologies such as Chemical Oxidation, Catalytic Oxidation, Photochemical Oxidation and Photochemical Catalytic Oxidation are analyzed in detail. Photochemical Catalytic Oxidation is the most desirable degradation technology for PAEs because of its mild reaction conditions and ideal degrade results. In the end, research and development of the degradation technologies for PAEs are prospected.
