| Combined with purification of silica gel column and determination by GC-MS,the extraction effects of microwave-assisted solvent extraction（MSE）,soxhlet extraction（SE） and ultrasonic extraction（UE） for polycyclic musk were studied.The extraction conditions of MSE were optimized.The optimal extraction conditions were as follows:extraction solvent:30 mL acetone-hexane（1∶1）,extraction time:20 min,temperature:120 ℃.Under the optimized conditions,the calibration curves of galaxolide(HHCB) and tonalide(AHTN) were liner in the range of 10-1 000 μg/L,with correlation coefficients of 0.999 5 and 0.996 4,respectively.The average recoveries of HHCB and AHTN were 84% and 89%,respectively,with RSDs of 11.2% and 9.2%.The detection limits were 0.71 μg/kg for HHCB and 0.68 μg/kg for AHTN.The result indicated that,compared with other extraction methods,the MSE method had obvious advantages in extraction effect,extraction time and organic solvent consumption, and was the best method for the extraction of polycyclic musk in soil at this stage. |
