The sorption of Pb2+ on the composite sorbent obtained by incorporating of copper(II)-potassium hexacyanoferrate or nickel(II)-potassium hexacyanoferrate and magnetite into sulphonated phenolic resin was studied. The sorption kinetics were performed in hydrochloric, nitric and sulphuric acid solutions in the concentrations range from 10-4 molźdm-3 to 1 molźdm-3. The distribution coefficients for the lead(II) sorption on the sorbents in these conditions were determined. The highest Kd values, more than 1000 cm3źg-1, were obtained for composite sorbents CuNCFM from HCl, HNO3 and H2SO4 (range concentration 10-4-10-2) and for CuNCF and NiNCF from HCl (range concentration 10-4-10-2). Also, the lead(II) sorption on the magnetite-loaded resin was performed.
