Adsorption de Pb(II), Cd(II) ET Cu(II) en solution par la zéolite Na-P1

Written by sctunisie no comments

Zeolite Na-P1 obtained by hydrothermal treatment from Aidoudi clay (south of Tunisia) has been used to adsorb Pb2+, Cd2+ and Cu2+ from aqueous solutions. Isothermal exchange curves have been determined at 25°C and pH 2, 3.5 and 5. They have been interpreted by the Langmuir model. Equilibrium constants related to the exchange of H+, Na+ and the different cations have been determined.
