摘要

本研究探讨了经臭氧老化的聚苯乙烯多孔材料的形态特性及其吸附行为。本研究使用浓度为 1.4 mg/L 的臭氧对 PS MPs 进行了 1 小时的老化，随后使用多种实验室技术研究了老化 PS MPs 的形态特征和吸附行为。研究结果表明，PS MP 的形态特征在老化过程中发生了变化。具体而言，PS 颗粒的尺寸从 3.284 μm 减小到 3.238 μm，ZP 值从 - 45.6 mV 减小到 - 76.3 mV。此外，与新鲜样品相比，老化 MP 的官能团发生了明显变化。与吸附率为 69.79% 的新鲜 PS 相比，老化 PS 对 CV 染料的吸附率也更高，达到 76.55%。老化 PS 的形态特征和吸附行为的改变可归因于这些污染物的聚合物结构降解以及其表面吸附位点的增加。由此可以得出结论，老化过程增强了 PS 的环境反应性和污染物吸附潜力。

Effect of ozonation on the morphological characteristics and adsorption behavior of polystyrene microplastics in aqueous environments

This study investigated the morphological properties of PS MPs aged by ozone and their adsorption behavior. In this study, the aging of PS MPs was carried out using ozone at a concentration of 1.4 mg/L for 1 h. Subsequently, various laboratory techniques were used to study the morphological characteristics and adsorption behavior of the aged PS MPs. The findings indicated that the morphological characteristics of PS MPs changed as a result of the aging process. Specifically, the size of PS particles decreased from 3.284 to 3.238 μm, while their ZP decreased from − 45.6 to − 76.3 mV. Furthermore, changes in the functional groups of aged MPs were evident when compared to fresh samples. Aged PS also had a higher adsorption rate for CV dye, at 76.55%, compared to fresh PS, which had an adsorption rate of 69.79%. The alterations in the morphological characteristics and adsorption behavior of aged PS can be attributed to the degradation of the polymer structure of these pollutants, as well as the increase in adsorption sites on their surfaces. It can be concluded that the aging process enhances the environmental reactivity and pollutant adsorption potential of PS.
