摘要
药物是水中普遍存在的一类微量新污染物,它在一定浓度下可对环境、动物和人体造成危害。常规的污水处理工艺难以有效地将其去除,吸附技术被认为在去除该类污染物方面具有潜力,但吸附剂的再生是瓶颈问题,亟需开发高效的吸附剂并实现吸附剂的再生和污染物的降解。综述了水中药物污染现状、水中药物类污染物的去除技术以及典型碳基纳米材料对药物的吸附和再生,在此基础上,提出了目前研究的不足,并指出今后的发展方向应为研发高效的碳基纳米复合吸附材料,研究其吸附特性和机理,以及再生过程中能够氧化降解所吸附的药物,同时实现高效吸附和吸附剂重复使用。
Pharmaceuticals are emerging organic contaminants in water,posing potential harm to environment,animals and human beings at low concentration.In cases where conventional wastewater treatment technologies are difficult to remove them effectively,adsorption technology is considered to have potential in pharmaceuticals removal.However,regeneration of adsorbents is a bottleneck problem.There is an urgent to achieve the goals of developing efficient adsorbents,regenerating adsorbents and degrading pollutants.This paper reviews the current status of pharmaceuticals pollutant and their removal technologies in water,adsorption and regeneration of typical carbonaceous nano-materials.On this basis,it identifies shortcomings in current research and proposes future development directions.Specifically,the focus should be on the development of efficient carbonaceous composite adsorption nano-materials,understanding their adsorption characteristics and mechanisms,and exploring methods for oxidizing and degrading the adsorbed pharmaceuticals during the regeneration process.The ultimate goal is to achieve both efficient absorption and regeneration simultaneously.
