Kinetics and Size Effects on Adsorption of Cu(II), Cr(III), and Pb(II) Onto Polyethylene, Polypropylene, and Polyethylene Terephthalate Microplastic Particles

Due to its small size, large specific surface area and hydrophobicity, microplastics, the adsorbed contaminants may together cause potential negative effects on ecosystems human beings. In this study, kinetics size adsorption of Cu(II), Cr(III), Pb(II) onto PE, PP PET microplastic particles were explored. Results indicated that PE microplastics have higher capacity for than microplastic. The was affected by types metal species. Among three metals, had largest amount particles, especially particles. Moreover, capacities increase with decrease particle size. <0.9 mm is greater 0.9–2 2–5 microplastics. effect More attention should be paid in case coexistence heavy metals tiny environment.
