abstract:
The polypyrrole-based imprinted membrane material was prepared on gold plated quartz wafer by potentiostatic method. The morphology, structure, and composition of membrane material were characterized by SEM, FT-IR, and XPS. The results show that the surface micromorphology of material was cauliflower-like, and the membrane contained H_2PO~-_4, which had the characteristics of H_2PO~-_4 imprinting. The exchange properties of H_xPO_4~((3-x)-) were investigated by electrochemical method. The results show that with the increase of pH, the ion exchange capacity first decreased and then increased, showing a “V” shape. As the concentration of NaH_2PO_4 increased, the ion exchange capacity monotonously increased, up to 150 mg/g.
