SZ-1型同位素X射线荧光分析仪分析多金属结核中锰铁钴镍铜

Determination of Mn, Fe, Co, Ni and Cu in Metal Nodule Using SZ-1 Isotope Excited X-ray Fluorescence Analyzer

摘要: 采用低分辨率能量色散Ｘ射线荧光分析仪和偏最小二乘法对太平洋多金属结核中的Ｍｎ、Ｆｅ、Ｃｏ、Ｎｉ和Ｃｕ等元素进行了现场分析，并对所用仪器的性能和方法的可靠性作了评价。方法经国家级标准物质验证，其测定值与标准值相符，ＲＳＤ（ｎ＝４２）各元素均小于１．０％，分析结果满足现场分析中矿物品位的测定要求。

Abstract: In situ analysis of Mn, Fe, Co, Ni and Cu in metal nodule by an isotope excited Xray fluorescence analyzer using partial least square (PLS) algorithm is reported in this paper. Performance and reliability test on the equipment and method are also discusse
