Analysis of Benzophenone in Sediment and Soil by Gas Chromatography/Mass Spectrometry
초록
Analytical method of benzophenone (BP) in sediment and soil was developed by gas chromatography/mass selective detector/selected ion monitoring (GC/MSD/SIM). The ultrasonic extraction of US EPA (method 3550B) method and liquid-liquid extraction for sediment and soil samples were used for the analysis of BP from sediment and soil. BP was extracted with n-hexane. Organic layer was washed with 5% sodium chloride solution. 1∼2 l of the concentrated solution of organic layer was applied to GC/MSD. The retention time of BP peak was 11.10 min. Recovery (%) of BP by ultrasonication from sediment and soil samples was 96.0∼100.6% and 40.0∼83.0%, respectively. Recovery of BP by liquid-liquid extraction was 51∼59% in soil samples. The detection limit of BP in sediment and soil samples were determined to 0.1 ng/g.
