摘　　要：根据国标GB/T16488-1996红外光度法测定水质中石油类和动植物油,对自动萃取仪萃取水中油类的萃取效率进行测定研究。探讨了不同条件及不同成分的油类污染物对萃取效率的影响。结果表明,氯化钠对四氯化碳萃取效率影响较大,食用油在四氯化碳中的萃取效率比在水中的高15%～20%。The extraction efficiency of oils in water by automatic extraction equipment was determinated by automatic extraction equipment,according to the national standard GB/T16488-1996. The effect on the extraction efficiency result from extraction condition and ingredient of oils pollutant was discussed.The results showed that the sodium chloride more affected extraction efficiency of carbon tetrarchloride.The extraction efficiency of edible oil in carbon tetrarchloride was higher15%～20% than in water.
