The studies on microplastics are significant in the world. According to the literature, microplastics have greatly specific surface areas, indicating high adsorption capacities for highly toxic pollutants in aquatic and soil environments, and these could be used as adsorbents. The influencing factors of microplastic adsorption, classification of microplastics, and adsorption mechanisms using microplastics for adsorbing organic, inorganic, and mixed pollutants are summarized in the paper. Furthermore, the influence of pH, temperature, functional groups, aging, and other factors related to the adsorption performances of plastics are discussed in detail. We found that microplastics have greater advantages in efficient adsorption performance and cost-effectiveness. In this paper, the adsorptions of pollutants by microplastics and their performance is proposed, which provides significant guidance for future research in this field.
关于微塑料的研究在全球具有重要意义。根据文献记载，微塑料具有极大的比表面积，这表明其在水生和土壤环境中对剧毒污染物具有很高的吸附能力，并且这些微塑料可用作吸附剂。本文总结了微塑料吸附的影响因素、微塑料的分类以及微塑料吸附有机、无机和混合污染物的吸附机制。此外，还详细讨论了pH值、温度、官能团、老化等与塑料吸附性能相关的因素的影响。我们发现微塑料在高效吸附性能和成本效益方面具有更大优势。本文提出了微塑料对污染物的吸附及其性能，为该领域未来的研究提供了重要指导。
