Fig. 6: Freundlich adsorption isotherm of Fe+3 in case of A. niger as biomass.
From: Biosorption removal of iron from water by Aspergillus niger
The isotherm was measured for initial values of iron (III) between 2.052 and 4811.98 mg/L, at room temperature, at optimum condition for the best adsorption (pH = 2.4, time of adsorption 60 min and for 4 g biomass).
