摘要

摘要: 从样品制备、仪器操作参数最佳化、内标补偿等几方面着手,利用两个标准物质(GSPN-2,GSPN-3)发展了大洋多金属结核中27种元素的等离子体质谱(ICP-MS)测定方法.这27种元素包括Ba,Ce,Co,Cu,Dy,Er,Eu,Gd,Ho,La,Li,Lu,Mo,Nd,Pr,Sb,Sc,Sm,Tb,Th,Tm,U,V,W,Y,Yb和Zn.各元素测定值与保证值相当吻合.对GSPN-2和GSPN-3,Ba,Sb,Sc,Y,Zn等5种元素可用外标校准法准确测定,其平均回收率(n=3)在91.4%～106.9%之间;可用内标(¹⁰³Rh)校准法准确测定其他22种元素,其平均回收率(n=3)在89.4%～110.2%之间;各元素3次测定的相对标准偏差(RSD)为0.0%～11.0%.

Abstract: A rapid and accurate method for 27 elements determination in polymetallic nodules by ICP-MS was developed on 2 standard reference materials of polymetallic nodules(GSPN-2 and GSPN-3).The 27 elements include Ba,Ce,Co,Cu,Dy,Er,Eu,Gd,Ho,La,Li,Lu,Mo,Nd,Pr,Sb,Sc,Sm,Tb,Th,Tm,U,V,W,Y,Yb and Zn.Mass interferences and matrix effects were properly reduced or compensated by careful sample preparation, instrumental operating parameters optimization and internal standard(103Rh) correlation.For the 27 elements in GSPN-2 or GSPN-3,the analytical results obtained were in good ag reement with the corresponding certified values with RSD % in the range of 0.0%~11.0%(n=3).The method can be conveniently applied to the analysis of real polymetallic samples.
