Selective solid-phase extraction of trace Pb(II) from aqueous solution using Pb(II)-ion imprinted polymer
In this work, we synthesized several ions imprinted polymers based on the inclusion of 8-hydroxyquinoline, vinyl benzoic acid, and diazoaminobenzene as ligands into the polymer matrix to complex with lead ions. Besides, to optimize various parameters for the selective extraction and enrichment of lead ions using the best synthesized imprinted polymers, the selectivity of the chosen inorganic ions was investigated. These investigations indicated that the synthesized imprinted polymer particles have good potential for selective enrichment of lead ions compared with other heavy metal ions, and the selectivity of lead ion-imprinted polymers for lead ion was higher than non-imprinted polymer.
