Rare earth elements were determined in 12 international standard reference rock samples using inductively coupled plasma mass spectrometry technique. Aim of this work was to find a relatively simple but reliable decomposition method for the purposes of REE determination. Sample solutions were produced by different sample decomposition methods: 1. closed vessel decomposition in a microwave digestion oven by different acid mixtures; 2. decomposition by LiBOj fusion in platinum crucibles. Effect of dilution was investigated. Final sample concentration of 0.2 gL' ' was found to be optimal. Indium was used as internal standard. HCI-HNO3-H2F2 digestion followed by an evaporation step was not efficient enough to obtain a total recovery. In the case of digestion with acid mixtures there could occur some recovery problems for the heavy REEs, mainly with the mixture of HCI-HN03-H2F2 which is less aggressive than the H1PO4-HNO3-H2F2 mixture, used alternatively. Fusion with UBO2 is a very simple process used extensively in our laboratory and gave good recovery data.
