This study evaluates the effectiveness of chemically treated sugarcane bagasse as an adsorbent for iron removal from water. The bagasse was modified using sodium hydroxide and citric acid, and its adsorption capabilities were characterized [1-3]. Batch adsorption experiments were conducted to determine the impact of initial iron concentration, contact time, pH, and adsorbent dosage. Results indicated that the treated sugarcane bagasse exhibited a significantly higher iron adsorption capacity compared to the raw material, with an enhancement factor of 1.7. Optimal conditions were identified as a contact time of 100 minutes, a pH of 3, and an adsorbent dosage of 1.5 grams. Adsorption isotherms were best described by the Langmuir model, yielding a maximum adsorption capacity (qmax) of 15.57 mg/g. Additionally, dynamic adsorption tests showed that the adsorbent could be reused effectively, with a desorption efficiency of 75.20%. These findings demonstrate that chemically treated sugarcane bagasse is a viable, cost-effective, and environmentally friendly option for iron removal in water treatment [4].
