| Résumé: | A continuous fixed-bed column study on coffee grounds was carried out at bed depths 0.5-2 cm, flow rates of 0.18-0.53 mL.min-1with initial orange acid II concentrations of 20-100 mg.L-1 at room temperature. The breakthrough time of fixed-bed increased with the increase in bed depth, which permitted orange acid II to diffuse more into the interior of coffee grounds. But decreased with increasing initial concentration, and flow rate.The experimental data were in good agreement with both Thomas and Yoon-Nelson models |
