摘要：
We have investigated the use of montmorillonite modified with polyethylenimine for the removal of ions of heavy metals from aqueous solutions. It has been found that such composite sorbent is rather promising for purifying wastewaters with pH > 3. The adsorption capacity of modified montmorillonite with respect to ions of ferrous iron ascends in the series: Cu(II) > Pb(II) > Ni(II) ≥ Zn(II) > Co(II) ≥ Cd(II).
