Abstract: A novel molecularly imprinted polymer (MIP) with high selectivity for sulfonamides was synthesized using reverisible addition fragmentation chain transfer (RAFT) polymerization technique with 2-cyanoprop-2-yl-dithionaphthalate as RAFT reagent, sulfadimethoxine as template, methacrylic acid (MAA) as functional monomer. The obtained MIP was characterized by static adsorption and the results indicated that the MIPs had high adsorption affinity to sulfonamides. The MIP was sucessfully empolyed as the adsorbtion sorbent of solid phase extraction for enrichment and clean-up four sulfonamides from food samples. Under the optimized conditions, good linearities were ranged from 0.010-10 μg/mL with r2=0.9991.The recoveries at three spiked levels were ranged from 91.0-110.2% with RSD less than 5.8%.
