Abstract
This study investigates the effectiveness of orange peels as a natural adsorbent for the removal of chromium (Cr³⁺ ) ions from aqueous solutions. The adsorbent was prepared by drying and pulverizing orange peels into a fine powder. The removal efficiencies of (Cr³⁺ ) were studied as a function of contact time, adsorbent dosage, pH, and initial metal ion concentration. Batch adsorption experiments were conducted, and data were analyzed using adsorption is other models such as Langmuir and Freundlich. The results demonstrated that orange peels have a high adsorption capacity for both (Cr³⁺ )ions, making them a cost-effective and environmentally friendly solution for heavy metal remediation. The study highlights the potential of agricultural waste as a sustainable material for water treatment applications.
