Abstract

In the present study, a simple and efficient preconcentration method was developed using carrier mediated three phase liquid phase microextraction prior to HPLC-UV for simultaneous extraction and determination of trace amounts of highly hydrophilic tetracycline antibiotics including tetracycline (TCN), oxytetracycline (OTCN) and doxycycline (DCN) in bovine milk, human plasma and water samples. For extraction, 11.0 mL of the aqueous sample containing TCNs and 0.05 M Na(2)HPO(4) (9.1<or=pH<or=9.5) was filled into a 12.0-mL vial. The solution of 1-octanol (containing 10% (w/v) of Aliquat-336 as carrier) was immobilized in the pores of a porous polypropylene hollow fiber. Aqueous receiving phase (RP, 24 microL of 0.1M H(3)PO(4) and 1.0M NaCl with pH=1.6) was located inside the lumen of hollow fiber and the fiber was transferred into the aqueous sample. After the extraction period, the receiving phase was directly injected into HPLC. In order to obtain high extraction efficiency, the parameters affecting the liquid phase microextraction were evaluated and optimized. Under the optimized conditions, the calibration curves were linear in the range of 0.5-1,000 microgL(-1) for TCN and OTCN, and in the range of 5-1,000 microgL(-1) for DC...Continue Reading
