ICP-AES法测定蒙古扁桃叶片中元素含量

Determination of Elements in the Leaves of Prunus Mongolica by ICP-AES

用HNO3-HClO4消解体系对蒙古扁桃叶片进行消解制样,利用电感耦合等离子体发射光谱法(ICP-AES)同时测定了蒙古扁桃叶片中Ca,Mg,Fe,Mn,Cu,Zn,Al,Sr,Sn和Pb等十种元素的含量,加标回收率为93%～110%,RSD为0.33%～2.94%。结果表明,该方法快速、简便、数据准确可靠,结果令人满意,为其综合开发利用提供科学依据。

For determination of elements in the leaves of Prunus mongolica,the samples were digested by nitric acid-perchloric.The contents of Ca,Mg,Fe,Mn,Cu,Zn,Al,Sr,Sn and Pb in the leaves of Prunus mongolica were determined by ICP-AES,at the same time a blank experiment was carried out.The results showed that the recovery rate of the ten elements was between 93% and 110%,and the relative standard deviation was between 0.33% and 2.94%.This method is fast,simple and accurate.
