The academic paper explores the efficacy of plant-derived polysaccharides, specifically from fenugreek and okra, as nontoxic and eco-friendly alternatives to traditional synthetic polymers for removing microplastics from various water sources. The research details the extraction and characterization of these natural polymers, followed by bench-scale experiments conducted on simulated, groundwater, freshwater, and ocean water samples. Utilizing optical microscopy, scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), and ζ-potential measurements, the study assesses the microplastic removal efficiency and confirms a bridging mechanism for flocculation. The findings consistently demonstrate that these plant-based polysaccharides outperform commercial polyacrylamide in microplastic removal, suggesting a promising sustainable solution for water treatment.
