Abstract

The main purpose of this study was to obtain kinetic and equilibrium parameters for  the anthraquinone dye removal of Remazol Brilliant Blue R dye from aqueous solutions using yeast biomass as biosorbent, and identify the functional groups responsible for biosorption by infrared spectrometry. Biosorption dye kinetics at temperatures of 10  °C,    20  °C, 30  °C  and 40 °C  were fitted  correctly  by  the pseudo-first  and pseudo-second  order  models.  The values of thermodynamic activation parameters indicated  that the biosorption process is endothermic  and no spontaneous.  Sorption isotherm at 20  °C, pH  2,0 and a biomass concentration of 1,0 g  L-1 was obtained,  finding  a value of 127,6 mg g-1 for the saturated monolayer according to  the Langmuir model. Infrared  studies showed that  carboxyl and amide are the main functional groups responsible for dye biosorption.

Keywords: remazol R brilliant blue, biosorption, yeast biomass.
