As emerging contaminants, microplastics (MPs) and antibiotics are often detected simultaneously in the water environment, and antibiotics in the water environment are often found on the surface of MPs. MPs can absorb, collect and carry various organic pollutants in water environment through surface adsorption and migration. Compared with the original MPs, the aging MPs has stronger adsorption capacity due to smaller particle size, larger specific surface area, and more adsorption sites. The environmental aging mode of MPs and the adsorption behavior of MPs on various antibiotics in water environment after aging were mainly reviewed, The aging method of MPs and the influencing factors and adsorption mechanism of antibiotics was summarized, and prospects for the aging problem of MPs and the effect on antibiotic adsorption was put forward.
