Application of Polysaccharide-Based Biosorbent Derived from Agricultural Waste for Removal of Dye and Pharmaceutical Pollutants from Effluents
Abstract: This study evaluated a polysaccharide-based biosorbent prepared from agricultural waste for the removal of dye and pharmaceutical pollutants from simulated effluents. Cellulose, starch, and pectin were extracted from fruit and vegetable peels, cross-linked using citric acid, and stabilized by lyophilization. Part of the biosorbent was encapsulated in calcium alginate beads using ionotropic gelation. Pollutant removal efficiency for safranin, aspirin, and paracetamol was assessed spectrophotometrically. The encapsulated biosorbent showed improved removal efficiency, achieving 61% for safranin, 40% for aspirin, and 85.2% for paracetamol, compared with the non-encapsulated form. Reusability performance was also better in the encapsulated system. Microbial combination experiments produced selective improvement only for aspirin with E. coli, while Corynebacterium diphtheriae showed limited effectiveness for paracetamol removal. The findings indicate that agricultural waste-derived biosorbents offer a promising, sustainable, and economical strategy for pollutant removal in wastewater treatment applications.
