本工作采用溶液试样,在标准中不加入基体,亦不对被分析样品进行分离富集的ICP-AES 等效浓度差减法,测定纯铂中十三个杂质元素。方法简便、快速、准确、并能节省大量的铂。
In this work, ICP-AES equivalent concentration subtraction method was used to separate the sample from the matrix without adding matrix in the standard. Thirteen impurity elements in pure platinum were determined. Method is simple, fast, accurate, and can save a lot of platinum.
