| Abstract: | The thallium content of eighty-seven geochemical reference samples has been determined by atomic absorption spectrometry using an air-acetylene flame or a graphite furnace atomizer, after extraction of thallium as chloride with methylisobutylketone (MIBK). A comparison with published data show clearly the need for much more data on most reference samples. |
