| 英文摘要 | a novel functional monomer t-ipts, 3-isocyanatopropyltriethoxysilane (ipts) bearing thymine (t) bases, was synthesized for imprinting hg2+. then a novel hg2+ ionic imprinted polymers (iips) based on thymine-hg2+-thymine (t-hg2+-t) interactions, i.e. hg-iips-t, were prepared by sol-gel process for the first time in this work. the hg-iips-t exhibited excellent selectivity towards hg2+ over cd2+, zn2+ pb2+, co2+, mn2+, mg2+ and ca2+, due to the specific t-hg2+-t interactions with high selectivity and high affinity. accordingly, hg-iips-t were used as solid-phase extraction (spe) sorbents for preconcentration of trace hg2+ in water samples, and satisfactory recoveries ranging from 95.2 to 116.3% were obtained. also, under optimized conditions, preconcentration factor and detection limit were achieved of 200 and 0.03 mu g l-1, respectively. the iips-t-spe proved to be a rapid and high-effective cleanup and enrichment method for trace hg2+ in water samples. more importantly, these results indicated that devising and synthesizing new functional monomers tailor-made for template would become a general promising way to improve the selectivity and stability of iips. 2012 elsevier b.v. all rights reserved. |
