Dispersive Liquid-Liquid Microextraction of Antibacterial Agent

Researchers from Universidad de Santiago de Compostela (Santiago de Compostela, Spain) developed a dispersive liquid-liquid microextraction sample preparation method to determine the antibacterial agent triclosan and its environmental transformation product methyl triclosan in water samples.

Researchers from Universidad de Santiago de Compostela (Santiago de Compostela, Spain) developed a dispersive liquid-liquid microextraction sample preparation method to determine the antibacterial agent triclosan and its environmental transformation product methyl triclosan in water samples. The extraction used a ternary mixture of a disperser, an extractant, and a derivatization reagent. Simultaneous derivatization and concentration of both species was achieved. The analysis was performed using gas chromatography with tandem mass spectrometry.
