| Abstract: | A supported liquid membrane technique was used for the extraction and enrichment of propofol in a spiked sample of urine. An acidic solution of propofol and thymol as an internal standard was passed over the membrane and after enrichment the acceptor solution was analyzed by LC with an electrochemical detector. The acceptor and donor pH, flow-rate, and volume of donor and different membrane solvents were varied to optimize the extraction efficiency. The detection limit for 100 ml of a spiked urine sample was 10 ppt of propofol. |
