| Abstract: | Nine geochemical reference samples from various sources were analyzed for selenium. The method used was simplified with regard to the decomposition and selenium isolation from matrix. Selenium was determined by hydride-generation atomic absorption; after selenium isolation from the matrix no interferences are to be expected. The results are in good agreement with values obtained by other methods. |
