摘　　要：传统测量重油中的硫方法存在分析时间长、分析效率低、操作复杂、重复性差的缺点。应用X-射线荧光光谱仪测定重油中硫的含量,并将其结果与库仑滴定法测定结果相比较,偏差为0.004%,在GB/T 214-1996允许误差之内。试验表明,X-荧光法具有操作方便、速度快、重复性良好等优点。Traditional method used for determining sulfer content in heavy oil has some shortcomings,such as long analysing duration,low analysing efficiency,complex operation,and bad repeatability etc..Using X-ray fluoresence spectrometer to determine sulfer content in heavy oil,and comparing the measured results with that of Coulomb's tittrimetric method,the deviation to be only 0.004%.it is within the allowable error stipulated in National Standard GB/T 214-1996.The test shows that the X-ray fluoresence method has advantages as convenient operation,fast speed,and good repeatabilibity etc..
