摘要
采用毛细管电泳法(CE)成功的对油田注水中常用的Br^-、NO_2^-、NO_3^-、SCN^-四种示踪剂进行了分离和检测,对四种离子的分离度、重现性、检测限进行了讨论,并与化学容量法进行了对比,同时对分析条件的确立和样品的处理进行了筛选,均取得了满意的结果。
Four kinds of tracer often used in oilfield waterflooding, Br^-, NO_2^-, NO_3^- and SCN^- have been separated and tested successfully by capillary electrophoresis method. The degree of separation, repeatability and detectable limit of the four kinds of ions are discussed, and compared with the results of chemical volumetric method. Meanwhile, the confirmation of analysis conditions and samples'preparation are screened, which obtain acceptable results.
