SBSE Used in Triclosan Analysis

Scientists from Hoshi University (Tokyo, Japan) and the National Research Institute of Police Science (Chiba, Japan) employed stir-bar sorptive extraction (SBSE) and thermal desorption gas chromatography–mass spectrometry (GC–MS) for analyzing 5-chloro-2-(2,4-dichlorophenoxy)phenol, otherwise known as triclosan, in river water samples. In the SBSE method, a magnetic stir bar coated with polydimethylsiloxane was added to a 10-mL water sample, and the sample was stirred for 120 min at room temperature. The coated stir bar was then subjected to thermal desorption and GC–MS.
