EFFECT OF pH ON THE COAGULATION EFFICIENCY OF POLYAMIDE MICROPLASTICS USING CHITOSAN DERIVED FROM MUD CRAB SHELLS
AI summary Read the abstract
Scientists made a natural water treatment substance from crab shells (a seafood waste product) and used it to filter out tiny plastic particles called microplastics—the same kind found in synthetic fabrics that can end up in our water supply. When the water was slightly acidic, this crab-shell material removed over 91% of the plastic particles, suggesting an eco-friendly, low-cost way to help keep microplastics out of our drinking water in the future. More research is needed before this method reaches your tap, but it's a promising step toward reducing microplastic exposure using waste we'd otherwise throw away.
This study investigates the effect of pH on the coagulation performance of polyamide (PA) microplastics using chitosan derived from mangrove crab shell (Scylla serrata) as a natural coagulant. Chitosan was synthesized through demineralization, deproteinization, and deacetylation processes and characterized using Fourier Transform Infrared (FTIR) spectroscopy. The degree of deacetylation (DD) obtained was 81.15%, indicating successful conversion of chitin to chitosan. Coagulation experiments were conducted at pH 1–9 to determine the optimum condition. The results showed that pH significantly influenced the removal efficiency, with the highest efficiency achieved at pH 5 (91.9%), followed by a slight decrease at neutral and alkaline conditions. The lower efficiency at extreme acidic and basic conditions was attributed to suboptimal interaction between chitosan and microplastic particles. These findings demonstrate that chitosan derived from crab shell waste is an effective and environmentally friendly coagulant for polyamide microplastic removal, with optimal performance under mildly acidic conditions.

Scientists tested chitosan, a natural material derived from shellfish, as an eco-friendly way to remove polyethylene microplastics from water. Under the best conditions (pH 6.0 with 100 mg/L of chitosan), the treatment removed 81.5% of microplastics, offering a promising and environmentally safe approach to cleaning microplastic-contaminated water.
Proof-of-Concept of Chitosan–Cellulose Composite Filters for Microplastic Removal from Wastewater

Scientists made a low-cost water filter from shrimp shell waste (a material called chitosan) and tested how well it captures tiny plastic particles from water compared to regular paper filters. The chitosan filter caught more and smaller plastic bits than plain paper because the material actually attracts and holds onto plastic, not just physically blocks it—an early but promising step toward cheaper, sustainable ways to clean microplastics out of wastewater before it re-enters our environment and, potentially, our drinking water and food chain.
Interaction of chitosan with nanoplastic in water: The effect of environmental conditions, particle properties, and potential for in situ remediation
AI summary Read the abstract
Researchers tested chitosan — a natural polymer derived from shellfish — as a tool to aggregate and remove nanoplastic particles from water, finding it caused clumping at low doses but that high pH, dissolved organic matter, and surface chemistry of the plastics all affected its performance. The results suggest chitosan-based treatment has real potential for water remediation but requires careful tuning of environmental conditions.
