Synthesis and transport abilities of new membrane materials incorporating mono- and bi-pyrazolic compounds

The membrane materials were obtained by photopolymerisation of formulation that contain the active monomer spread on a polyacrylonitrile support. The facilitated transport and the extraction power of Cd(II), Pb(II) and Hg(II) through the synthesised membranes were reported. We have determined both the diffusion flux of different cations and the selectivity of the prepared membranes towards each cations.
