摘要
采用操作简单的基体匹配法和内标法校正基体,建立了一套完整的电感耦合等离子体质谱(ICP-MS)法检测镁合金中的铜、钴、银、铅、锑、铍、铬、铟、钇、镉、锰、钛、钽、镧、铈15种痕量元素.检出限、加标回收、精密度的相关试验表明,各元素的检出限范围为0.0039~1.6µg/L,加标回收率为95.1%~109.2%,精密度为0.2%~2.3%.方法简单、快速、高效,可满足市场上对镁合金中痕量元素的检测需求.
A complete set of inductively coupled plasma mass spectrometry(ICP-MS)was established to determined 15 trace elements including copper,cobalt,silver,lead,antimony,beryllium,chromium,indium,yttrium,cadmium,manganese,titanium,tantalum,lanthanum and cerium in magnesium alloys by simple matrix matching method and internal standard method.The test results showed that the detection limits of each element were in the range of 0.0039~1.6μg/L.The recoveries were 95.1%~109.2%.The precision was 0.2%~2.3%.The method is simple,fast and efficient,and can meet the market demand for the detection of trace elements in magnesium alloys.
