【Abstract】 A new method for the rapid determination of benzyl chloride in water has been established by coupling nonequilibrium solid phase microextraction (SPME) with gas chromatography mass spectrometry (GC MS). It takes only 15 minutes for the whole process. A manual SPME holder with 85 μm polyacrylate coating is used to extract benzyl chloride from water, It has a good linear range of 1～50 μg/L, the detection limit of 0.91 μg/L, and relative standard deviation of 9.86%. The method has been used to determine benzyl chloride in river water with satisfactory results.更多还原
