SORPTION OF LEAD(II) ON COPPER(II) AND NICKEL-POTASSIUM HEXACYANOFERRATES AND MAGNETIC-LOADED RESIN FROM INORGANIC ACID SOLUTIONSBarbara Kubica The Henryk Niewodniczański Institute of Nuclear Physics, Polish Academy of Sciences, 152 Radzikowskiego Str., 30-341 Kraków, Poland 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 mol·dm–3 to 1 mol·dm–3. The distribution coefficients for the lead(II) sorption on the sorbents in these conditions were determined. The highest Kd values, more than 1000 cm3·g–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. Close X |
