摘要
作为新兴的环境污染物,微纳米塑料在自然界广泛分布,其分析检测和环境转化是目前研究者们关注的重要问题。微塑料会通过某些吸附机制和环境中的有机污染物和重金属相互作用,成为化学污染物的载体。文章综述了微塑料对有机污染物吸附的作用机制(疏水作用、静电作用、氢键、孔隙填充、范德华力和π-π相互作用)以及影响因素,并对微塑料研究的发展方向进行了展望,以期为微塑料相关研究提供参考。
As a new type of environmental pollutants,Nano and microplastics are widely distributed in the natural world and difficult to degrade.The detection and environmental transformation of microplastics were focused on.Microplastics could interact with multiple chemicals including organic contaminants or heavy metals in the environment though certain sorption mechanisms,thus become vectors of hazardous chemicals.In this review,the sorption mechanisms of microplastics for organic pollutants,including hydrophobic interactions,electrostatic interactions,hydrogen bonding,pore-filling,VanderWaals forces,andπ-πinteractions were summarized.Meanwhile,the factors strengthening or weakening these mechanisms were also reviewed in detail.Finally,the development direction of microplastics research was prospected in order to provide reference for related research.
