Coconut husk, sugarcane bagasse, and orange peels are examples of agricultural waste products that can be used as biosorbent materials. In this work, coconut husk, sugarcane bagasse, and orange peels were employed as adsorbents to explore their potential to adsorb zinc, nickel, and chromium. Zinc, nickel, and chromium ions were adsorbed in a batch adsorption experiment employing various parameters, including contact duration (30, 60, 90) minutes, pH (5, 6, 7, 8) and adsorbent dosage (5, 10, 15) g. Adsorption of zinc, nickel, and chromium will be optimized using raw coconut husk, sugarcane bagasse, and orange peels at various contact times, pH levels, and adsorbent dosages. In general Orange peel showed greater adsorption efficiencies than Coconut husk and Sugarcane bagasse. Adsorption of Chromium on Orange peel, Coconut husk and Sugarcane bagasse was very fast and more efficient than Zinc and Nickel. The maximum adsorption efficiencies for Zinc, Nickel and Chromium on Coconut husk, Sugarcane bagasse and Orange peel are found to be 59.33% for Orange peel, 57.17% for Coconut husk and 69.02% for Orange Peel In conclusion, raw coconut husk, Sugarcane bagasse and orange peels can adsorb zinc, nickel and chromium ions from aqueous solutions.
