Acid-base and metal-based potentiometric titration methods were used to analyze sorption mechanisms of lead by Rhizopus arrhizus fungal biomass. Biosorption was not considered globally but as the result of successive sorption reactions on various binding sites with different selectivities. Precipitation occurred rapidly when lead concentration increased. Lead was sorbed essentially by carboxylic groups and by phosphates and sulfonates (less abundant) of the organic matter. The lead affinity to… CONTINUE READING

The lead affinity to carboxylic , sulfonate and phosphate binding sites depended on the association coefficient with proton or counter - ion and on the spatial distribution of the surface sites promoting the formation of mono- or bi - dentate complexes .
