微塑料与磷界面相互作用机制及其环境效应研究进展
Interfacial Interaction Mechanisms and Ecological Implications of Microplastics and Phosphorus in Aquatic and Terrestrial Ecosystems:A Review
摘要
Abstract
As emerging macromolecular environmental pollutants,microplastics(MPs)and their interfacial interactions with the key biogenic element phosphorus(P)significantly im-pact nutrient cycling in aquatic and terrestrial environments.From the perspectives of inter-facial chemistry and physical chemistry,the adsorption thermodynamics and kinetics of phosphate onto MPs with diverse polymer matrices were systematically reviewed and the mi-croscopic coupling mechanisms modulated by multiple environmental factors were thorough-ly elaborated.The results indicated that pristine MPs exhibit low polarity and limited ad-sorption capacity.However,following environmental weathering(e.g.,photo-oxidation and hydrolysis),abundant oxygen-containing functional groups were generated on MP sur-faces accompanied by increased specific surface area.Accordingly,the phosphorus adsorp-tion pathway shifted from simple physical pore filling to complex interfacial chemical proces-ses dominated by chemical complexation(ligand exchange,hydrogen bonding)and bridging coprecipitation mediated by multivalent metal cations(Ca2+,Fe3+).Furthermore,such ad-sorption behaviors were strongly regulated by solution pH,ionic strength and dissolved or-ganic matter(DOM).Serving as highly mobile chemical carriers,MPs drastically interfered with the cross-interface transport and internal release of phosphorus via dynamic adsorption-de-sorption equilibria.Future research should strengthen in-situ characterization under cou-pled multi-stress conditions and explore physicochemical mechanisms in multi-pollutant composite systems.关键词
