Physisorption and Chemisorption Mechanisms Influencing Micro (Nano) Plastics-Organic Chemical Contaminants Interactions: A Review

Microplastics, which serve as sources and vector transport of organic contaminants in both terrestrial marine environments, are emerging micropollutants increasing concerns due to their potential harmful impacts on the environment, biota human health. Microplastic particles have a higher affinity for hydrophobic high surface area-to-volume ratio, particularly aqueous conditions. However, recent findings shown that concentrations adsorbed microplastic surfaces, well fate through distribution ecological risks, largely influenced by prevailing environmental factors physicochemical properties aquatic environment. Therefore, this review article draws scientific literature discuss inherent polymers typically used plastics different contaminants, compositions, factors, polymeric influence variability sorption capacities. Some specific points discussed (a) an appraisal types, composition environment; (b) critical assessment mechanisms major influencing contaminants-micro (nano) (MNPs) interactions; (c) evaluation capacities chemical MNPs terms characteristics including hydrophobicity, Van der Waals forces, π–π bond, electrostatic, hydrogen bond (d) overview dynamics behind microplastics-organic interactions using kinetic isothermal models. Furthermore, insights into future areas research gaps been highlighted.
