Benzophenone (BP) type UV filters are common environmental contaminants that are posing a growing health concern due to their increasing presence in water. Different studies have evidenced the presence of benzophenones (BP, BP-1, BP-2, BP-3, BP-4, BP-9, HPB) in several environmental matrices, indicating that conventional technologies of water treatment are not able to remove them. It has also been reported that these compounds could be associated with endocrine-disrupting activities, genotoxicity, and reproductive toxicity. This review focuses on the degradation kinetics and mechanisms of benzophenone-type UV filters and their degradation products (DPs) under UV and solar irradiation and in UV-based advanced oxidation processes (AOPs) such as UV/HO, UV/persulfate, and the Fenton process. The effects of various operating parameters, such as UV irradiation including initial concentrations of HO, persulfate, and Fe, on the degradation of tested benzophenones from aqueous matrices, and conditions that allow higher degradation rates to be achieved are presented. Application of nanoparticles such as TiO, PbO/TiO, and SbO/TiO for the photocatalytic degradation of benzophenone-type UV filters was included in this review.
二苯甲酮（BP）类紫外线吸收剂是常见的环境污染物，由于其在水中的存在日益增多，对健康的威胁越来越大。不同的研究已经证明了几种环境基质中存在二苯甲酮（BP、BP-1、BP-2、BP-3、BP-4、BP-9、HPB），这表明传统的水处理技术无法去除它们。据报道，这些化合物可能与内分泌干扰活动、遗传毒性和生殖毒性有关。本综述重点介绍了在紫外线和太阳辐射下以及在基于紫外线的高级氧化工艺（AOPs）如 UV/HO、UV/过硫酸盐和芬顿工艺中，二苯甲酮型紫外线吸收剂及其降解产物（DPs）的降解动力学和机制。介绍了各种操作参数（如紫外线照射包括初始浓度的 HO、过硫酸盐和 Fe）对水基质中测试的二苯甲酮的降解影响，以及可以实现更高降解速率的条件。本综述还包括了纳米颗粒如 TiO、PbO/TiO 和 SbO/TiO 用于二苯甲酮型紫外线吸收剂的光催化降解的应用。
