    In zinc and cadmium hyperaccumulator plant, Potentilla griffithii roots showed Zn and Cd accumulation of 14,060 and 9098 mg/ kg of DW, respectively, at Biosorption of Cu(II), Ni(II), Zn(II) and Pb(II) ions from,2017-8-25 · pH. Previous studies also reported that the maximum bio-sorption efficiency of Cu(II), Ni(II), Zn(II), and Pb(II) ions on biomass was observed at pH 6.0–7.0. Effect of biosorbent dose The biosorbent dosage is an important parameter because this determines the capacity of a biosorbent for a given initial concentration.
