Utilization of fruit waste for treatment of wastewater

Water pollution is an environmental crisis that requires sustainable, cost-effective remediation. Mango peels and kernels are used to make activated carbon for water filtration in this study. Phosphoric acid activation, drying, and sieving produced activated carbon. To assess AC adsorption effectiveness, ash, moisture, pH, and iodine number were measured. UV spectrophotometry was used to test mango peel and mango kernel AC adsorption of Methylene blue dye. Over time, mango peel AC showed great dye adsorption efficiency, demonstrating its microporous nature and attraction to organic contaminants. The complete hardness reduction trials showed mango peel AC could remove hardness-inducing ions from water. Functional groups responsible for adsorption efficiency were confirmed using infrared spectroscopy. The findings suggest mango peel-derived activated carbon is an eco-friendly and cost-effective water treatment material. Future wastewater treatment research should optimize activation factors and assess large-scale applications.
