Evaluation of Three Operational Parameters in Adsorption Process of Organic Dyes

The present research was focused on the synthesis of a new material and on the evaluation of its adsorptive capacity. Powder of cherry stones (waste product of fruit industry) was entrapped on chitosan (a natural polymer). The developed product performance was assessed for the elimination of an organic dye (Acid Red 66). The experimental results reveal that the produced composite can be a viable solution for the treatment of colored aqueous effluents. Under optimized conditions (pH 2, adsorbent concentration: 100 g/L, working temperature: 30 °C), the manufactured adsorbent was able to retain more than 95 % of the target pollutant.
