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。
The elements of Mn, Fe, Co, Ni and Cu in the polymetallic nodules of the Pacific Ocean were analyzed on-site by low-resolution energy dispersive X-ray fluorescence analyzer and partial least squares method. The performances of the instruments used and the reliability of the method Made a comment. The method was verified by national standard materials. The measured values are consistent with the standard values. The contents of all the elements in RSD (n = 42) are less than 1.0%. The analysis results meet the requirements of mineral content determination in the field analysis.
