Abstract :
In the present paper, we will present the synthesis of new methacrylic monomers by the action of methacryloyl chloride on two pyrazole tripods. The synthesis of new membrane material incorporating the pyrazole tripod N, N- [3- (1,5-dimethylpyrazolyl) methyl] -2-aminoethanol in their structure and we will study the facilitated transport of heavy metals (Cu^2+, Pb^2+ and Cd^2+) through this synthesized material. We have determined both the membrane is selective to the facilitated transport of heavy metals Pb^2+ and Cd^2+ relative to Cu^2+,!such that the flux ratios are: FPb^2+/ FCu^2+ = 4.5; FCd^2+ / FCu^2+ = 4.2 and FPb^2+ / FCd^2+ = 1.1.
