The characterization of the dyes adsorption on granular particles of Cunninghamella elegans lyophilized biomass is reported. The adsorption process regarded a typical acid bath for wool and each of the three dye-components Acid Blue 62, Acid Red 266 and Acid Yellow 49. The process was characterized in terms of adsorption isotherm and of adsorption kinetics. Effects of granular size and initial pH have been assessed. The maximum adsorption capacity of lyophilised biomass with respect to Acid Blue 62, Acid Red 266, Acid Yellow 49 and to the model wastewater were 480, 210, 210 and 530 mgdye/gDM, respectively. A mutual interference among adsorbed dyes resulted. The adsorption kinetics for the Acid Blue 62 resulted of the first order type with a constant 0.85 - 0.27 h-1.

Abstract
The characterization of the dyes adsorption on granular particles of Cunninghamella elegans lyophilized biomass is reported. The adsorption process regarded a typical acid bath for wool and each of the three dye-components Acid Blue 62, Acid Red 266 and Acid Yellow 49. The process was characterized in terms of adsorption isotherm and of adsorption kinetics. Effects of granular size and initial pH have been assessed. The maximum adsorption capacity of lyophilised biomass with respect to Acid Blue 62, Acid Red 266, Acid Yellow 49 and to the model wastewater were 480, 210, 210 and 530 mgdye/gDM, respectively. A mutual interference among adsorbed dyes resulted. The adsorption kinetics for the Acid Blue 62 resulted of the first order type with a constant 0.85 - 0.27 h-1.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
