Heavy Metal Adsorption Using Cellulose Xanthate from Sugarcane Bagasse: A Fixed-Bed Column Study

Year: 2025

Type: article

Abstract: In recent years, various environmentally friendly adsorbents have been developed to address the removal of heavy metals from industrial wastewater. This study focuses on the adsorption of lead (Pb²⁺) and copper (Cu²⁺) using cellulose xanthate derived from sugarcane bagasse as an adsorbent. The adsorption experiments were conducted in a fixed-bed column with dimensions of 2.4 cm in diameter and 8 cm in height. Atomic Absorption Spectrophotometry (AAS) was used to analyze the concentrations of Pb²⁺ and Cu²⁺ before and after adsorption, while the adsorbent composition was characterized using X-Ray Fluorescence (XRF). The breakthrough times for Pb²⁺ and Cu²⁺ adsorption was found to be 8 and 6 minutes, respectively, with total adsorption durations of 18.584 and 17.543 minutes. The Thomas Model was employed to evaluate the kinetics and adsorption capacity, yielding kinetic constants (KTH) of 0.00283 and 0.0006 mL/mg.min for Pb²⁺ and Cu²⁺, respectively, and adsorption capacities (qeq) of 712.89 and 181.18 mg/g. These results provide valuable insights into the adsorbent’s efficiency, kinetics, and potential applications in environmental remediation and wastewater treatment.
