Keywords:
Biopolymer, Composite Materials, Pollutant Removal, Adsorption, Reusability.Abstract
This study investigated the synthesis, characterization, and performance evaluation of biopolymer-based composite materials for the removal of pollutants from wastewater. A biodegradable biopolymer was combined with a functional or reinforcing agent to create a stable composite with enhanced adsorption capabilities. The synthesized composite was thoroughly characterized using various analytical techniques to assess its functional groups, surface morphology, and structural features. Batch adsorption experiments were performed to analyze the influence of factors such as pH, contact time, adsorbent dosage, and pollutant concentration on removal efficiency. The results demonstrated that the composite displayed excellent adsorption properties, achieving a maximum pollutant removal efficiency of approximately 91% under optimized conditions. The adsorption process was marked by rapid initial uptake of pollutants, followed by attainment of equilibrium. Regeneration studies indicated that the composite maintained about 78–82% of its original removal efficiency after multiple cycles of use, highlighting its satisfactory reusability. Overall, the findings suggest that biopolymer-based composite materials represent an effective, eco-friendly, and sustainable solution for wastewater treatment and pollutant remediation.
