Sorption properties of hydrophobic organic chemicals to micro-sized polystyrene particles

Remediation of Contaminated Waters with Microplastics

“…Unfortunately, the q max values obtained for PAHs sorption using MPs as adsorbents are very low on the order of pg (Lin et al 2019), while Boving and Zhang (2004) report a maximum capacity of 74.67 mg/g for certain PAHs using wood fibers.…”

Sorption of chemical contaminants on degradable and non-degradable microplastics: Recent progress and research trends

“…This line of research has come a long way, focusing on chemical pollutants from a wide range of sources. We have divided the recent progress of the interaction of chemical pollutants and microplastics based on the type of chemical, source or commercial use: Flame retardants (Chen et al, 2019;Xu et al, 2018a;Seidensticker et al, 2018), metals (Besson et al, 2020;Guo et al, 2020aGuo et al, , 2020bWang et al, 2020aWang et al, , 2020bWang et al, 2021;Zhou et al, 2020b;Zon et al, 2020;Zou et al, 2020), PAHs (Li et al, 2020;Lin et al, 2019;Wang et al, 2019;Zhao et al, 2020), PBDEs (Wu et al, 2020a(Wu et al, , 2020bXu et al, 2019), PCBs (Lin et al, 2019;Zhan et al, 2016), PHCs (Qiu et al, 2019;Zhang et al, 2019), Phthalate esters (Liu et al, 2019a(Liu et al, , 2019b(Liu et al, , 2019c, personal care products (Dong et al, 2019;Ho and Leung, 2019;Li et al, 2019;Wu et al, 2020aWu et al, , 2020bZhang et al, 2018aZhang et al, , 2018b, pesticides (Gong et al, 2019;Šunta et al, 2020;Tubić et al, 2019), pharmaceuticals (Guo et al, 2018(Guo et al, , 2019a(Guo et al, , 2019b…”

Adsorption and Desorption Behaviour of Polychlorinated Biphenyls onto Microplastics’ Surfaces in Water/Sediment Systems

“…This phenomenon was also observed by Pascall et al [21] using PS film, where the diffusion coefficient decreased with the increase of molar volume of PCBs. The main hypothesis is that PCBs diffuse into PS particles through the static boundary layer around the PS particle [18]. This is an easier process for molecules with lower molar volume, like PCB-28 or PCB-52.…”

“…First, PCBs are adsorbed on the particle surface by weak van der Waals interactions. Then, PCB molecules further diffuse inside the glassy polymeric structure of MPLs like PS [18,23]. Once there, their desorption is less favoured because they are physically entrapped [23].…”

“…On the other hand, some studies conducted under controlled conditions assessed the adsorption of organic contaminants onto MPL surfaces [8,9]. In the case of PCBs, the parameters for the adsorption of PCBs have been studied to micro-PE and nano-PS in a system composed of plastic particles, PCBs, and water [18,19]. However, complementary studies in more realistic environmental scenarios, including sediments competing with the MPLs and the suspended organic material, are necessary to describe the adsorption/desorption behaviour of HOCs on MPL surfaces in aquatic systems.…”
