Abstract


In this work, the characteristics of low cost NaA zeolite membranes for heavy metal removal from synthesised solutions are presented. These membranes were elaborated on a clay macroporous support which were prepared and characterized by XRD, SEM and N2 permeation. The effects of synthesis parameters such as temperature T and time t on the proprieties of the NaA zeolite membranes were investigated. The best experimental conditions for synthezised membranes are obtained for T = 60 °C, t = 24 h and 117 L m-2 h-1 bar-1 for a water flux of membrane.
The tests for the removal of Pb(II), Zn(II) and Cr(VI), conducted on these NaA zeolite membranes, show respectively the rejection reached 99%, 99% and 12% after 1 hour of filtration at 7 bars of N2 and at ambient temperature.
