Article: Biosorption of copper and zinc from waste water using natural fruit cortex Journal: International Journal of Environment and Waste Management (IJEWM) 2026 Vol.40 No.2 pp.133 - 147 Abstract: Our environment is negatively affected by water contamination issues specifically by heavy metals. Among the most harmful pollutants in the environment, heavy metals have devastating impacts on human health. A wide range of industrial and mining operations result in the discharge of these pollutants into the environment. The most dangerous heavy metals widely used in industry are cadmium, zinc, lead, chromium, and copper. Due to their high cost and ineffectiveness at low concentrations, conventional water treatment technologies for metal removal are generally constrained. Toxic contaminants must be removed in an environmentally responsible manner. A variety of 'biosorbents' have been used to effectively remove harmful metals from the environment. The use of inactivated biomass as an adsorbent presents an appealing prospective alternative to their current approaches because of the extensive availability of these materials. The goal of this work is an investigation into the removal of copper and zinc from banana and mango cortexes. Adsorbent dosage, pH, contact time, and initial metal ion concentration all had an effect on adsorption capacity. In this comparative study we have compared and found that mango cortex behaves as a very good heavy metal adsorbent in comparison to banana cortex.

Due to their high cost and ineffectiveness at low concentrations, conventional water treatment technologies for metal removal are generally constrained. Toxic contaminants must be removed in an environmentally responsible manner. A variety of 'biosorbents' have been used to effectively remove harmful metals from the environment. The use of inactivated biomass as an adsorbent presents an appealing prospective alternative to their current approaches because of the extensive availability of these materials. The goal of this work is an investigation into the removal of copper and zinc from banana and mango cortexes.
