Mechanistic investigation of the mass transfer stages involved during the adsorption of aqueous lead onto Scopulariopsis brevicompactum fungal biomass

The Scopulariopsis brevicompactum fungal biomass (SFB) was applied as an adsorbent for the uptake of aqueous lead species via the dynamic sorption process. The adsorption capacity dependence on the solution pH, contact time, initial adsorbate concentration and adsorbent concentration was investigate...
