| Abstract: | The solid-phase microextraction（SPME）using C8-SBA-15 fiber coating coupling with high performance liquid chromatography（HPLC） was applied to determine the trace in environment water.The experimental conditions of SPME,such as extraction time,extraction temperature,desorption time were optimized.The optimized conditions were as below：room temperature,400r/min of stirring rate,30 min of extraction time and 3min of desorption time,respectively.The linear range was 3.0—320μg/L,the limit of detection was 0.5μg/L.The sampling procedures were simple,rapid and solvent free,and the technique had high sensitivity and good precise. |
