Ionic liquid-molecularly imprinted polymers for pipette tip solid-phase extraction of (Z)-3-(chloromethylene)-6-flourothiochroman-4-one in urine
چکیده انگلیسی
A new type of ionic liquid-molecularly imprinted polymers (IL-MIPs) synthesized by precipitation polymerization using 1-allyl-3-methylimidazolium bromide and acrylamide as co-functional monomers and (Z)-6-fluoro-3-(hydroxymethylene)-thiochroman-4-one (FHO) as dummy template was successfully applied as a selective adsorbent of pipette tip solid-phase extraction (PT-SPE) for rapid extraction and determination of (Z)-3-(chloromethylene)-6-flourothiochroman-4-one (CFO) in urine. The factors that affected the extraction efficiency including amounts of adsorbent, types of washing solvent, and types and volumes of elution solvent were optimized. Under the optimum conditions of ionic liquid-molecularly imprinted polymers-pipette tip solid-phase extraction (IL-MIPs-PT-SPE) coupled with HPLC-UV, good linearity for CFO was achieved in a range of 0.1-10.0 μg mL−1 (r = 0.9999) and the recoveries at three spiked levels were ranged from 94.8% to 103.4% with the relative standard deviations (RSDs) less than 5.7% (n = 3).
