摘要
微塑料比表面积大、疏水性强的特点使其能与有机污染物发生吸附-解吸作用,该作用能改变有机污染物的环境行为。综述微塑料的性质(种类、粒径、老化程度)和环境因素(pH、温度、盐度、溶解有机质)对微塑料的比表面积、疏水性及其与有机污染物的相互作用的影响,并从有机结构、电负性、pH等方面分析和总结微塑料吸附过程中涉及的机理(分配、疏水、π-π相互作用、氢键作用、静电作用等)。
The characteristics of large specific surface area and strong hydrophobicity enable microplastics have adsorption-desorption effect with organic pollutants,which can change the environmental behavior of organic pollutants.The effects of physicochemical properties of microplastics(types,size,aging degree)and environmental factors(pH,temperature,salinity,dissolved organic matter)on the specific surface area,hydrophobicity of microplastics and their interaction with organic pollutants were reviewed.The mechanism(distribution,hydrophobicity,π-πinteraction,hydrogen bond interaction,electrostatic interaction,etc)involved in the adsorption process of microplastics were analyzed and summarized from the aspects of organic structure,electronegativity and pH.
