摘要
本法采用湿消解法处理样品,一次处理可测定钾、钠、钙、镁、铁、锰6种元素,在测定钙、镁时需加氯化镧作为释放剂。各元素检测限优于GBW5413.21标准要求。回收率在98%~102%之间。本方法准确可靠,特别适合于批量测定。
This act process samples using wet digestion method, Once the process can be measured the six elements of the potassium, sodium, calcium, magnesium, iron, manganese, determination of calcium, magnesium, lanthanum chloride to be added as a release agent. Detection limit of each element is better than the GBW5413.21 standard requirements. The recovery rate is between 98% to 102%. The method is accurate and reliable, especially suitable for batch determination.
