Abstract

The chelating ion exchange resin AFM was synthesized by condensation of anthranilic acid with formaldehyde and m-cresol in DMF media at 100 oC ± 6

C. The identification of resin structure was performed by elemental and FTIR analysis. The thermodynamic parameters such as activation energy Ea, entropy S

, enthalpy H

and free energy G

for thermal decomposition were calculated from thermal data. The morphology of AFM resin shows transition material between crystalline and amorphous phase. The rate of exchange was rapid. i.e. t1-2 < 22 min for PbII and pH dependence of exchange of metal ions on the resin has been determined for several metal ions NiII, CuII, ZnII, CdII and PbII. Successive separations and recovery of some pair of metal ions PbII-CdII, PbII-ZnII and ZnII- CuII have been performed by using distribution coefficient Kd.
