微塑料的老化及其对水环境中抗生素的吸附行为研究进展

微塑料(microplastics, MPs)和抗生素作为新兴污染物，经常在水环境中能被同时检测到，并且水环境中的抗生素也经常在MPs表面被发现。MPs可以通过表面吸附和迁移，吸收、聚集并携带水环境中的各类有机污染物而受到广泛关注。与原始MPs相比，老化后的MPs因粒径变小、比表面积增大，从而吸附位点增多，而具有更强的吸附能力。主要从MPs的环境老化方式、老化后MPs对水环境中各类抗生素的吸附行为展开了综述，总结了老化MPs的老化方法及吸附抗生素的影响因素及吸附机理，并对MPs老化问题及对抗生素的吸附影响提出展望。

Review on Aging of Microplastics And Their AdsorptionBehavior to Antibiotics in Water Environment

Antibiotics have become one of the main organic pollutants in the water environment due to their excessive use and mass discharge.As a new type of pollutant, microplastics (MPs) and antibiotics are often detected in water environment, and antibiotics in the water environment are often found on the surface of MPs . In addition, MPs in water environment has strong adsorption due to its small particle size, strong hydrophobicity, high stability and fluidity, and can absorb, gather and carry various organic pollutants in water environment through surface adsorption and migration, which has attracted wide attention.In this paper, the environmental aging of MPs the influence of aging,MPs on the adsorption behavior of antibiotics in water environment, as well as the factors affecting the adsorption were summarized. Finally, the future research direction of the aging of MPs and the adsorption direction of antibiotics in water environment were analyzed and prospected.
