Determination of synthetic musk in ground water by liquid-liquid extraction-gas chromatography mass spectrometryEI北大核心CSCD

A gas chromatography-mass spectrometry GC-MS method was established to determine three different synthetic musksSMsfrom ground water. Dichloromethane as the extracting solventthe concentrated extracts were tested by GC-MS using the external standard quantitative method. Each sample was extracted three times with 40 mL dichloromethane respectively. The linearity test was carried out in the range of 20.0 to 2000 μµg/L the relative standard deviationRSDRRFof average relative response factor was less than 8.7%and the limits of detectionLODswere in the range of 0.007 to 0.012 μµg/L. The recoveries of three spiked ground water samples were all between 98.1% and 117.0%and the relative standard deviations were less than 13%. Musk xylene in the ground water sample was 0.013 μµg/Land the spiked real sample had the recoveries higher than 80%. This method was suitable for the detection of trace SMs in ground water. © 2022, Youke Publishing Co.,Ltd. All rights reserved.
