The concentrations of Ru, Pd, Ir, Pt, and Au were determined in a ferromanganese nodule reference sample NOD-A-1 by inductively coupled plasma mass-spectrometry. Sample preparation procedures include acid digestion and anion exchange preconcentration. Standard addition method was used to eliminate losses of the analyte during the chromatographic separation. The results are in agreement with previously published data. The low level of intermediate precision for Au between different subsamples of the same sample probably originates from the heterogeneous distribution of Au in ferromanganese nodules. The accumulation of PGE in ferromanganese nodules was studied using international reference samples.  相似文献

A measurement procedure for determining of Ru, Pd, Ir, Pt and Au mass fractions in ferromanganese deposits by inductively coupled plasma‐mass spectrometry after acid digestion and anion exchange preconcentration is presented. To eliminate incomplete recovery after sorption preconcentration of the platinum‐group elements (PGE) and Au, a standard addition method was used. Detection limits ranged from 0.02 ng (Pd, Ir) to 0.19 ng (Ru). The measurement results for ferromanganese nodule reference material NOD‐A‐1 and NOD‐P‐1 agree with earlier reported values. Intermediate precision of PGE concentration data for nodule reference materials in this work was 5–24% (1s) and could reflect sample heterogeneity.  相似文献
