Adsorption in column of Cu (II), Ni (II) and Pb (II) with resin XAD-7 impregnated with bis (2-ethylhexyl) ammonium bis (2-ethylhexyl) dithiocarbamate (BEABEDC) in aqueous solution

The extraction of copper, nickel and lead in mini-column pack of resin XAD-7, impregnated with BEABEDC was realized by varying the concentration of metallic solution, flow rate of elution in the case of copper in order to carry out the kinetic exchanges which govern the system. These experiments were carried out in acidic region. Extraction chromatography is combined with the spectrometer of atomic absorption for analysis of solution collected after extraction. The experimental data have been integrated into Langmuir adsorption model. Cu (II) can be desorbed using H2SO4 4M when the temperature is elevated to 50°C.
