Microplastics, small sized plastic particles having size <5 mm are formed through primary process including production of beauty products, microbeads and microfibres as well secondary mechanical weathering, friction, aberration fragmentation large plastics. The major sources microplastics land-based ocean-based sources. Microplastic pollution is a serious concern due to the persistent, low biodegradability bio-accumulative behaviour. Microplastics can bioaccumulate in food chain cause ecological human health risk. Hence, it important remove from aquatic ecosystems. removed systems wastewater series processes such physical, chemical biological treatments. In present articles, >250 articles reviewed collect information regarding various methods for removal microplastics. Also, probable control strategies combat with were assessed. It was concluded that recent water treatment efficient removing microplastic pollution. efficiencies ranged between 74 %-99.2 %, 65 %-99.20 % 77 %-100 methods, respectively. Among three physical especially filtration biochar most way (efficiency up 100 %) also creating public awareness, promoting reusing, recycling reducing, application bioplastics wastes. This review will be useful add current knowledge abatement pollution, finding novel solution help policymakers implement effective cost-efficient method microplastics, find out new reduce, reuse recycle

Adsorption of Organic Pollutants from Wastewater Using Chitosan-Based Adsorbents

Polymers, Год журнала: 2025, Номер 17(4), С. 502 - 502

Опубликована: Фев. 14, 2025

Among the naturally occurring polysaccharides, chitosan is second-most abundant polysaccharide. It obtained from chitin through a process known as deacetylation. biodegradable, biocompatible, and non-toxic, which made it suitable for various environmental applications. In present review, structure, properties, characteristics of were discussed. addition, modified forms (including cross-linked, nanoparticles, functionalized, grafted chitosan) enumerated. The applications these in adsorption organic pollutants (such antibiotics, dyes, pesticides, microplastics, polyaromatic hydrocarbons, parabens, polychlorobiphenyls) are comprehensively reviewed. Furthermore, mechanism adsorption, isotherm (Langmuir Freundlich), kinetic models highlighted. Finally, economic viability assessment impact processing tons shrimp shells into annually

Key adsorbents and influencing factors in the adsorption of micro- and nanoplastics: A review

Journal of Environmental Management, Год журнала: 2025, Номер 383, С. 125394 - 125394

Опубликована: Апрель 22, 2025

Microplastics and nanoplastics (MNPs) are emerging contaminants in drinking water sources that pose serious risks to human health ecosystems. Several removal strategies, such as adsorption, exist but present challenges for their industrial scalability. This review provides a concise overview of MNP adsorption mechanisms highlights the limited critical exploration column literature, emphasizing its importance large-scale applications. Special attention is given carbon-based materials due cost-effectiveness, environmental friendliness sustainability. Other adsorbents (e.g., metal-organic frameworks, clays) also discussed promising performance realistic matrixes. To predict optimize efficiency adsorbents, leading simulation models reviewed. Taken together, this work comprehensive fundamental factors, mechanisms, adsorbent selection experimental conditions, adsorption. By highlighting underexplored area column-based processes, it valuable information advance viable industrial-scale solution contamination.
