Removal of Iron (II) from Aqueous Solutions Using Natural Adsorbent

Iron (Fe) contamination in water poses significant environmental and health risks due to its persistence and potential toxicity. This study investigates the use of Vitisvinifera (grape branch stem powder) as a low-cost, eco-friendly biosorbent for the removal ofFe(II) ions from aqueous solutions. Batch experiments were conducted to examine the effects of pH, contact time, adsorbent dosage, initial metal concentration, and temperature on the adsorption process. The biosorption occurred through mechanisms such as ion exchange, electrostatic attraction, and surface complexation, facilitated by functional groups like hydroxyl and carboxyl present in the biomass. The results demonstrated effective Fe(II) removal, with optimal conditions observed at lower pH and moderate temperatures. The study highlights the potential of Vitisvinifera as a sustainable alternative to conventional treatment methods for iron-contaminated water.
