矿物材料去除水中抗生素的研究进展

Research progress of antibiotic removal from water using mineral materials

近年来,水中新兴污染物引发的环境问题越来越受到人们的重视。抗生素属于新兴污染物之一,其难降解、用量大且无法被完全吸收利用。残留的抗生素排放到水环境中逐渐积累,给生态环境造成不良影响。矿物材料具有成本低、处理工艺简单等优点,被广泛用于去除水中的抗生素。对抗生素在环境中的危害进行介绍,描述了抗生素进入不同水环境的方式,同时对黏土、金属矿物及其他矿物材料去除水中抗生素的方法进行总结,并对不同材料的去除能力进行比较。黏土矿物的吸附作用、Fenton反应以及光催化反应均能有效去除水中的抗生素。在实际应用中,应根据抗生素的含量选择合适的处理方法,并注意不同工艺之间的相互配合。

In recent years,environmental problems caused by emerging pollutants in water have attracted increasing attention.As one of the emerging contaminants,antibiotics are difficult to degrade,in large amounts,and cannot be fully absorbed and utilized.Residual antibiotics are discharged into the environment and gradually accumulate,causing adverse effects on the ecological environment.Mineral materials are widely used to remove antibiotics from water because of their low cost and simple treatment process.The hazards of antibiotics in the environment,and the ways in which antibiotics enter different water environments were described.The removal of antibiotics from water by clay,metallic minerals and other mineral materials were summarized and the removal capacities of different materials were compared.It was found that the adsorption of clay minerals,Fenton reaction and photocatalytic reaction could effectively remove antibiotics from water.In practical application,appropriate methods should be selected according to the content of antibiotics,and attention should be paid to the cooperation between different processes.
