摘要：A kind of sulfanilic acid molecularly imprinted polymer (MIP) was synthesized by reverisible addition fragmentation chain transfer (RAFT) process using (4-cyanopentanoic acid)-4-dithiobenzoate (CTA-2) as chain transfer reagent, methacrylic acid (MAA) as functional monomer and hydrophobic ionic liquids, 1-butyl-3-methylimidazolium hexfluorophosphate ([bmim]PF6), as functional reaction medium. The results showed that the obtained MIPs had regular shape with high affinity to sulfonamides, and when it was empolyed as the adsorbtion sorbent of solid phase extraction for selectively extracted the three kinds of sulfonamides (sulfamerazine, sulfadiazine and sulfamethoxazole) from chicken samples, the interferences of chicken matrix could be eliminated efficiently and the recoveries at three spiked leves were satisfied. © (2013) Trans Tech Publications, Switzerland.
