摘　　要：采用紫外荧光法测定4种不同原油及轻质石脑油中的硫含量,仪器的最佳条件为:气化段温度800℃,裂解段温度1000℃,氧气流量400m L·min^(-1),氩气流量100m L·min^(-1)。方法的检出限为0.03mg·L^(-1)。测定了方法的精密度,相对偏差为1.20%。以4个油样为基体,测得加标回收率在96.5%~100.7%之间。分析结果表明,不同地域的原油及轻质石脑油中的硫含量存在较大的差异。The sulfur content of 4 kinds of crude oil and naphtha light naphtha was determined by ultraviolet fluorescence.The optimal gasification temperature was 800℃,cracking temperature was 1000℃,O2 flow rate was 400 mL/min and Ar flow rate was 100 mL/min.Detection limit was 0.03mg/L and the RSD was 1.2%.Recovery rate of four kinds of oil sample was 96.5%~100.7%.The analytical results showed that the sulfur content had large difference between different crude oil and light naphthaa.
