    ABSTRACT: A liquid phase microextraction method using hollow fiber to support extraction solvent was developed for enrichment of trace level chloroanilines in environmental water samples. Target analytes, 2-chloroaniline, 3-chloroaniline, 2,3-dichloroaniline, 2,4-dichloroaniline, 3,4-dichloroaniline, and 3,5-dichloroaniline were determined using gas chromatography-flame ionization detector after extraction. Experimental conditions that affect extraction efficiency were investigated and optimized. The proposed method showed a wide linear range from lower μgL−1 to 1,000μgL−1, low detection limits (≤5.1μgL−1), and reasonable relative standard deviations (RSDs<13%). Feasibility of the method was evaluated by analyzing river water samples collected from the Hudson River and the East River in New York City.
