摘要/Abstract

摘要： 微塑料来源广泛,老化后其物理化学性质会发生明显改变,表现出与原生微塑料不同的行为特征,对生态环境产生潜在的风险。该文概述了老化微塑料的来源及老化特征,综述了关于微塑料老化对其在环境中的吸附行为及光敏行为影响的研究进展。微塑料老化后表面形貌、官能团、结晶度的改变会影响其比表面积、内部高分子链排列、润湿性、表面电荷、与污染物间的静电相互作用等,进而影响其对环境中有机物、金属离子的吸附行为。同时,微塑料光老化产生的环境持久性自由基和活性氧化物会影响微塑料的自氧化过程,也会对有机物的光敏行为产生影响。最后该文着眼于当前相关研究的不足之处,对今后研究的重点方向进行展望,以期为未来老化微塑料的相关研究提供参考。

Abstract: Microplastics can come from a wide range of sources. The physical and chemical properties of microplastics change significantly after aging and exhibit distinct behavior characteristics from that of the original microplastics, which causes potential risks to ecology. This study summarizes sources and characteristics of aged microplastics, and reviews the research progress on the effect of aging of microplastics on its adsorption and photosensitive behaviors. The change of surface morphology, functional groups and crystallinity of microplastics after aging can affect specific surface area, internal arrangement of polymer chain, wettability, surface charge and electrostatic interaction with pollutants. Furthermore, the change has influenced on the behavior of microplastics on the adsorption of organic compounds and metal ions in the environment. In addition, the environmental persistent free radicals and reactive oxygen species generated by the photoaging of microplastics not only affect self-oxidation process of microplastics, but also impact the photosensitive behavior of organic compounds. Finally, focusing on research gaps of previous researches, the future research focus and direction are prospected, so as to provide references and suggestions for the future researches on aged microplastics.
