摘要：

In this study, the adsorption behavior of lead (Pb(II)) onto environmentally-relevant tire wear particles (TWP) gained by natural weathering and mechanical abrasion, ultraviolet-aged polylactic acid microplastics (UV-PLA), and ultraviolet-aged polystyrene microplastics (UV-PS) was compared to investigate the difference of representative microplastics between the adsorption capacity and mechanism. Our results indicated that the aging processes significantly improved the adsorption capacity to Pb(II), and TWP had the highest adsorption amount, fo...
