Abstract

In the present work a lyophilised cell suspension of Rhgizopus arrhizus was studied as biosorbent material for SELENITE removal from aqueous solutions.The biomass was firstly characterised by potentiometric titration and evaluation of the major ionic content. The experimental data highlight that the biomass cell wall contains two main acidic groups with a total amount of 5meq/g. Equilibrium BIOSORPTION trials of SELENITE were carried out to investigate the effects of two important experimental factors, pH and biomass concentration. SELENITE BIOSORPTION extent was repressed by pH decrease. The effect of the biomass concentration changes both with the equilibrium pH value and the kind of oxyanion adsorbed. In the case of SELENITE BIOSORPTION at pH>5, the increase of biomass concentration causes a diminution of the maximum specific oxyanion uptake, due probably to cell aggregation phenomena. Equilibrium modeling was performed as reported in this paper. Analyses of FTIR showed that SELENITE adsorbed on extracellular of biomass.
