建立了用单扫描示波极谱同时测定原油中镍和铜含量的方法。确定了最佳底液体系 ,绘制了工作曲线 ,进行了干扰实验和回收率实验。应用此方法测定了胜利及大港原油中镍和铜的含量。结果表明 ,本法具有灵敏、快速、价廉、线性范围宽、稳定性好、共存离子无干扰等特点 ,完全适用于原油中镍、铜含量的同时测定 A method for the simultaneous determination of nickel and copper in crude oil by single-sweep oscillopolarography was established. The optimum bottom liquid system was determined, the working curve was drawn, the interference experiment and the recovery experiment were carried out. This method was used to determine the contents of nickel and copper in Victory and Dagang crude oil. The results show that this method is sensitive, fast, inexpensive, wide linear range, good stability, coexistence of ion interference characteristics, fully applicable to the simultaneous determination of nickel and copper in crude oil
