鲜魔芋及其种植土壤中矿物元素的ICP-AES法测定

Determination of Mineral Elements in Konjak and Its Growth Soil by ICP-AES

采用电感耦合等离子体原子发射光谱法 (ICP_AES)测量了不同产区鲜魔芋球茎及其种植土壤中10种矿物元素的含量 ,并初步讨论其相关性 ;采用湿法消化处理样品并考察了不同元素测定的精密度、回收率 ;测定的相对标准偏差(RSD)均小于2 %,回收率为95 %～104 %,结果可信度高。

Contents of10mineral elements in konjak and its growth soil were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES)and the relativity of contents of the elements between konjak and its growth soil were preliminarily discussed.The relative standard deviations(RSD)and recoveries of the elements were presented.The recoveries of95%～104%and relative standard deviations of less than2%were obtained.So the obtained results are reliable.
