摘　　要：简要介绍了在水中矿物油的测定过程中,无水硫酸钠铺垫厚度对石油醚萃取液脱水过滤速度及水样测定结果的影响,得出了水样污染越重,石油醚萃取液中含的水份越多,无水硫酸钠铺垫厚度应适当加厚,但测定结果仍满足环境监测要求的结论。This paper deals with the influence of Na2SO4 matting thickness on velocity of dehydrating filter and test result during the testing petroleum in water. It concludes that water content in ligroin＇s extract is more and more covariant with water polluted and Na2SO4 matting thickness, but the testing result is still suitable for environment monitoring.
