摘要：

The adsorption behavior of iridium on an cw-amino pyridine (AP) resin at very low Ir concentrations (0.24 ng ml(-1)) was studied by using the Ir-192 radiotracer technique. A preconcentration procedure was established, and the overall yield was 91.0 +/- 1.8% for Ir. Inductively coupled plasma mass spectrometry (ICP-MS) has been applied to the measurement of Ir in reference materials, and a good agreement between the reference values and our results was obtained. This method is also suitable for the analyses of trace Au and Pd in environmental and geological samples. (C) 2000 Elsevier Science B.V. All rights reserved.
