光催化降解烷基酚类内分泌干扰物研究进展

Review on photocatalytic degradation of alkylphenols endocrine disruptors

烷基酚类内分泌干扰物(APs)是环境内分泌干扰物(EDCs)的一种,属于持久性有毒化学污染物,因其不易降解、伪持久和生物累积的特性而受到了科学界的广泛关注。传统的废水处理方法无法对其进行有效去除,而光催化氧化技术作为一种新型高级氧化技术,近年来被广泛应用于处理新兴污染物。对最典型的烷基酚类内分泌干扰物(壬基酚和辛基酚)进行了介绍,综述了传统宽带隙光催化剂及其复合材料和新型窄带隙可见光催化剂降解APs的研究进展,并对其未来的发展趋势进行了展望。

Alkylphenols endocrine disruptors(APs)are one of the environmental endocrine disrupting chemicals(EDCs),which are persistent toxic chemical pollutants.They have been widely concerned by the scientific community because of their non-degradable,pseudo-persistent and bioaccumulative characteristics.Traditional wastewater treatment methods cannot effectively remove APs.As a new advanced oxidation technology,photocatalysis has been widely used to treat emerging pollutants in recent years.Focusing on the most typical alkylphenol endocrine disruptors(nonylphenol and octylphenol).The research progress of traditional wide band gap photocatalysts and their composites and new narrow band gap visible light photocatalysts for APs degradation were reviewed,and the future development trend was prospected.
