摘要: 综述了原油中含氮化合物的分离富集及鉴定方法,着重介绍了吸附色层法、酸抽提法、离子交换树脂法和络合法等分离富集方法的研究进展,并对以上各种方法的优缺点进行了讨论。原油中含氮化合物主要采用气相色谱-质谱(GC—MS)、气相色谱-原子发射检测器(CC—AED)、气相色谱-氮磷检测器(GC—NPD)、气相色谱-氮化物特定检测器(GC—NSD)和火焰电离检测器(FID)等技术进行分析鉴定。Abstract: The separation and quantification technologies of nitrogen - containing compounds in crude oil, emphasizing on adsorption chromatography, acid extraction , ion exchange and complexing are reviewed. The advantages and disadvantages of these methods are dis
