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 H2PO4-, which had the characteristics of H2PO4- imprinting. The exchange properties of HxPO4(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 āVā shape. As the concentration of NaH2PO4 increased, the ion exchange capacity monotonously increased, up to 150 mg/g.
