摘要: The presence of anions in solution was found to inhibit the uptake La/sup 3 +/, Cd/sup 2 Pb/sup UO/sub 2//sup and Ag/sup +/ by Rhizopus arrhizus biomass. effects ranged from total inhibition at equimolar concentrations EDTA no change or 12-fold molar excesses Cl/sup -/ CO/sub 3//sup -/. No anion enhance metal levels, degree generally followed series: greater than equal SO/sub 4//sup PO/sub glutamate chemical equilibrium model REDEQL2 adapted treat R. biomass use predict solution. Comparisons with experimental result are made discussed light assumptions underlying model.
