Contrasting effects of microplastic aging upon the adsorption of sulfonamides and its mechanism

The aging behavior of microplastics (MPs) is unavoidable in the natural environment, but the mechanisms underlying the differences in MP aging affecting the adsorption performance of different MPs remain unclear. In this work, the adsorption characteristics of sulfonamides (SAs) on virgin MPs (thermoplastic polyurethanes (TPUs), polyamides (PAs)) and aged MPs were determined under simulated conditions (ultraviolet (UV), ultraviolet combined...
