新型无机吸附剂对水中塑化剂的去除研究进展

Research progress of the removal of plasticizer from water using new inorganic adsorbent

邻苯二甲酸酯(PAEs)是一种广泛使用的塑化剂,可用于建材、食品包装、医疗器械和化妆品等领域。PAEs同时也是内分泌干扰素,近年来在工业废水、生活污水、垃圾渗滤液、地表水和地下水中均有检出,其具有生物富集性,可诱发多种疾病,对人体健康构成威胁。吸附法是去除水中PAEs的主要技术之一,具有操作简便、应用灵活的特点。在众多吸附剂中,以无机吸附剂的性能最佳,也最有潜力实现工业应用。除传统吸附剂活性炭外,生物炭、碳纳米管、石墨烯、改性Si/Al分子筛等新型无机吸附材料近年来也被用于水体中PAEs的去除。详细介绍了新型无机吸附剂在去除水中PAEs中的应用情况,探讨了不同吸附剂的优缺点,并对其发展趋势进行展望。

As a widely used plasticizer,phthalates(PAEs) are used in building materials,food packaging,medical devices and cosmetics. PAEs are also endocrine disruptors and have been detected in industrial wastewater,domestic sewage,landfill leachate,surface water and groundwater in recent years,which are bioconcentrated and can induce various diseases,posing a threat to human health. Adsorption is one of the main techniques for the removal of PAEs from water,which has the characteristics of easy operation and flexible application. Among different kinds of adsorbents,inorganic adsorbents have the best performance and the most potential for industrial applications. In addition to the traditional adsorbent activated carbon,new inorganic adsorbents such as biochar,carbon nanotubes,graphene,and modified Si/Al molecular sieves have been used for the removal of PAEs from water in recent years. The application of new inorganic adsorbents in the removal of PAEs from water was described in detail,the advantages and disadvantages of different adsorbents were discussed,and their development trends were also prospected.
