| Abstract: | A method was established for determinating rubidium in geological samples by inductively coupled plasma mass spectrometry(ICP-MS), with which the content of rubidium was measured by ICP-MS after the samples were dissolved with a mixed acid of HCl-HNO3-HF-HClO4 in an open container. The method was applied to the determination of rubidium in soil or rock, with a detection limit of 3.2 ng/g, relative standard deviation less than 3% and the recovery by standard addition method ranging from 90% to 120%. |
