Polysaccharide nanocomposites in wastewater treatment: A review

Chemosphere, Journal Year: 2023, Volume and Issue: 347, P. 140578 - 140578

Published: Nov. 6, 2023

In modern times, wastewater treatment is vital due to increased water contamination arising from pollutants such as nutrients, pathogens, heavy metals, and pharmaceutical residues. Polysaccharides (PSAs) are natural, renewable, non-toxic biopolymers used in the field of gas separation, liquid filtration, adsorption processes, pervaporation, proton exchange membranes. Since addition nanoparticles PSAs improves their sustainability strength, nanocomposite has gained significant attention for past decade. This review presents a comprehensive analysis PSA-based nanocomposites efficient treatment, focusing on adsorption, photocatalysis, membrane-based methods. It also discusses potential future applications, challenges, opportunities photocatalysis. Recently, have shown promise adsorbents biological-based systems, effectively removing metals that could hinder microbial activity. Cellulose-mediated successfully removed various wastewater, including dyes, oil, organic solvents, pesticides, Thus, PSA would support biological processes plants. A major concern discharge antibiotic wastes industries, posing environmental health risks. PSA-mediated bio-adsorbents, like clay polymeric hydrogel beads, efficiently remove antibiotics ensuring quality ecosystem balance. The successful use bio-adsorbents depends ongoing research optimize application evaluate impacts. Implementing these eco-friendly large scale holds great significantly reducing pollution, safeguarding ecosystems, protecting human health.
