Accelerated aging of polyvinyl chloride microplastics by UV irradiation: Aging characteristics, filtrate analysis, and adsorption behavior
Wang, Kefu; Wang, Kangkang; Liang, Siqi; Guo, Changyan; Wang, Wei; Wang, Jide (Journal article; Peer reviewed, 2023)The extensive use of plastic products by people has led to the prevalence of microplastics (MPs) in aquatic and terrestrial ecosystems. MPs will be able to undergo multiple aging processes and release dissolved organic ... -
Adsorption Behavior of Diclofenac on Polystyrene and Poly(butylene adipate-co-terephthalate) Microplastics: Influencing Factors and Adsorption Mechanism
Liang, Siqi; Wang, Kangkang; Wang, Kefu; Wang, Tao; Guo, Changyan; Wang, Wei; Wang, Jide (Journal article; Peer reviewed, 2023)To unveil the intricacies surrounding the interaction between microplastics (MPs) and pollutants, diligent investigation is warranted to mitigate the environmental perils they pose. This exposition delves into the sorption ... -
Adsorption of Diclofenac Sodium by Aged Degradable and Non-Degradable Microplastics: Environmental Effects, Adsorption Mechanisms
Liang, Siqi; Wang, Kangkang; Wang, Kefu; Kou, Yuli; Wang, Tao; Guo, Changyan; Wang, Wei; Wang, Jide (Journal article; Peer reviewed, 2023)Microplastics (MPs) are novel pollutants, which can carry toxic contaminants and are released in biota and accumulate. The adsorption behavior of MPs and aged MPs has attracted extensive attention. In this paper, the aging ... -
Adsorption–desorption behavior of malachite green by potassium permanganate pre-oxidation polyvinyl chloride microplastics
Wang, Kefu; Wang, Kangkang; Chen, Yaoyao; Liang, Siqi; Guo, Changyan; Wang, Wei; Wang, Jide (Journal article; Peer reviewed, 2023)Microplastics (MPs) and the typical hydrophilic organic pollutant Malachite green (MG) are frequently detected in sewage treatment plants. Potassium permanganate (KMnO4) pre-oxidation is an economical and effective technology ... -
Comparing the adsorption of methyl orange and malachite green on similar yet distinct polyamide microplastics: Uncovering hydrogen bond interactions
Wang, Kangkang; Kou, Yuli; Wang, Kefu; Liang, Siqi; Guo, Changyan; Wang, Wei; Lu, Yi; Wang, Jide (Journal article; Peer reviewed, 2023)Microplastics (MPs) and dye pollutants are widespread in aquatic environments. Here, the adsorption characteristics of anionic dye methyl orange (MO) and cationic dye malachite green (MG) on polyamide 6 (PA6) and polyamide ... -
Competition adsorption of malachite green and rhodamine B on polyethylene and polyvinyl chloride microplastics in aqueous environment
Zhong, Yiping; Wang, Kangkang; Guo, Changyan; Kou, Yuli; hassan, afaq; Lu, Yi; Wang, Jide; Wang, Wei (Journal article; Peer reviewed, 2022)Microplastics (MPs) will cause compound pollution by combining with organic pollutants in the aqueous environment. It is important for environmental protection to study the adsorption mechanism of different MPs for pollutants. ... -
Desorption of sulfamethoxazole from polyamide 6 microplastics: Environmental factors, simulated gastrointestinal fluids, and desorption mechanisms
Wang, Kefu; Wang, Kangkang; Chen, Yaoyao; Liang, Siqi; Zhang, Yi; Guo, Changyan; Wang, Wei; Wang, Jide (Journal article; Peer reviewed, 2023)Microplastics (MPs) can enrich pollutants after being released into the environment, and the contaminants-loaded MPs are usually ingested by organisms, resulting in a potential dual biotoxic effect. In this paper, the ...
