摘要
ICP/AFS是1981年美国Baird公司研制的,该仪器是以ICP作原子化池,以脉冲空心阴极灯作激发源进行元素的荧光测定,具有干扰少,线性范围宽等优点,但目前尚未见应用于地质样品分析的文献。本文针对地质样品的特点,对仪器的各种参数.
A method has been proposed to determine Ag, Mg, Sr and Zn in rocks and minerals in a medium of nitric and La-tartaric acid. Optimum measurement conditions have been established. More than 30 elements (except large amounts of Si and Al) do not interfere Ag, Mg, Sr and Zn interfere each other. Detection limits: 0.96 ppb for Mg, 2.1 ppb for Ag, 1.1 ppb for Sr, 0.8 ppb for Zn.
