益菲佳口服液中微量元素分析方法研究

Study on the Content Determination of Trace Elements in PULMOCARE Oral solution

采用用硝酸—高氯酸(3∶1)混酸湿法消化处理样品,以硝酸锶作基体改进剂,消除基体对钙、镁离子的测定干扰,制订了乙炔—空气火焰原子吸收法测定益菲佳口服液中锌等微量元素的测定方法,取得了较好的回收率和精密度,方法操作简便、省时、结果准确。

With nitric acid- perchloric acid （3：1 ）mixed acid digesting PULMOCARE Oral solution sample, Zincum, calcium, magnesium, kalium and natrium were assayed by Acetylene - Air flame AAS using strontium nitrate as ionic release, Under the optimized conditions, the standard added recoveries and their RSD are the following respectively o This method was simple and accurate, It is suitable for the quality control of Zincum, calcium, magnesium, kalium and natrium in PULMOCARE Oral solution,
