摘要：
MRFX was used in the removal of Pb(II) and Cu(II) ions from aqueous solutions.MRFX included not only thiol groups, but also sulfonic groups with higher adsorption affinity sites.Adsorption isotherms and kinetics were used to address the adsorption mechanism.The adsorption capacities of Pb(II) and Cu(II) are 84 and 120 mg g−1, respectively.
