  Rezumat:   The purpose of this paper was to establish the optimum experimental conditions for removal of Congo Red (CR) from aqueous solutions by biosorption on alginate immobilized fir tree sawdust (Abies Alba) beads. The studies were carried out under various experimental conditions. Dye concentration, fir tree sawdust quantity, stirring rate and working regime were considered in order to assess their influence on the biosorption process. Removal efficiencies up to 97% were reached in the case of immobile phase regime. Also, adsorption capacity increased with a decrease in the sawdust quantity and an increase of the initial dye concentration. The results indicate that this local immobilized material can be an attractive option for dye removal from diluted industrial effluents.

Keywords: biosorption, Congo red, immobilized fir tree sawdust, alginate beads, kinetics
