摘  要:
建立了土壤中萘及其取代衍生物的加速溶剂萃取方法。土壤经石英砂分散后,装入加速溶剂萃取仪萃取池中,以二氯甲烷-丙酮(V/V,1∶1)为溶剂,在炉温100℃、压力10.3422 MPa条件下萃取10 min。萃取液经过K-D浓缩后,用氟罗里硅土小柱净化,用DB-5MS柱分离,以气相色谱-质谱定性定量检测。对空白土壤样品进行3种浓度水平的加标试验,其平均回收率为64.0%~102.6%,相对标准偏差为7.6%~15.2%。

摘  要:
A method that accelerated solvent extraction of naphthalene and its derivatives was carried out in this research. A soil sample, mixed with some silica sand, was placed in the extract cell. Objectives were extracted by dichloromethane-acetone(V∶V,1∶1) at extraction temperature of 100 ℃ and extraction pressure of 10.3422 MPa for 10 min. The eluent was purfied using florisil silica column after concentrated by K-D. Then naphthalene and its derivatives were analyzed by gas chromatography-mass spectrometry using a DB-5MS column. Spiked recoveries of three concentrations ranged from 64.0%~102.6% with relative standard deviation 7.6%~15.2%(n=7).
