| Abstract: | It is quite necessary to accurately determine hydrogen sulfide in crude oil,as it would corrode refinery equipment,pollute the environment and harm to human bodies.By optimizing experimental conditions,this work determined the heating temperature to be 60 ℃,and the flow rate of carrier gas to be 375 mL/min,which established a method for rapid determination of hydrogen sulfide in crude oil with liquid phase extraction.The recoveries and relative standard deviations of hydrogen sulfide in crude oil were in ranges of 92％ ～ 110％ and 2.13％ ～ 3.28％ (n =6),respectively.Therefore,this simple,rapid and reproducible method is suggested for direct determination of hydrogen sulfide in crude oil. |
