Preparation and Characterization of Pyridin-2-amine Functionalized Thiadiazole-Embedded Polymer Inclusion Membrane and Utilization of Its Heavy Metal Transport Efficiency

3-[5-(Cycloheximino)-4,5-dihydro-1,3,4-thiadiazol-2-yl]pyridine-2-amine was synthesized and used to make a novel pyrazole derivative embedded polymer inclusion membrane (Py@PIM). The surface and structure morphology of Py@PIM was detected using thermogravimetric analysis, FT-IR spectroscopy and scanning electron microscopy. Donnan dialysis system was also used to assess the transport efficacy of Py@PIM towards 5 heavy metals (Co, Cd, Cu, Ni, Pb). The results show that according to the kinetic coefficient, the order is Pb > Ni > Co > Cd > Cu. Similar kinetic order was also observed in multiple cation experiments, in experiments where all cations were mixed in a single cell.
