摘　　要：实验采用1-丁基-3-甲基咪唑四氟硼酸盐[Bmim][BF4]作为萃取剂,以邻二氮菲为显色剂,建立了离子液体萃取分光光度法测定微量铁的分析方法.同时优化了体系p H、离子液体用量等实验条件,并对生姜中的铁进行测定,方法准确度高.Trace iron in zingiber officinale rosc was determinated by spectrophotometry with l-butyi-3-memyilmlu- azolium tetrafluoroborate [ Bmim ] [ BF4 ] as an extractant and with phenanthroline as a chromogenic agent. The effect of pH, the amount of ion liquid and other conditions were optimized. Results show that the method has a high accuracy.
