Determination of arsenic in geological materials by electrothermal atomic-absorption spectrometry after hydride generation
Rock and soil samples are decomposed with HClO4—HNO3; after further treatment, arsine is generated and absorbed in a dilute silver nitrate solution. Aliquots of this solution are injected into a carbon rod atomizer. Down to 1 ppm As in samples can be determined and there are no significant interferences, even from chromium in soils. Good results were obtained for geochemical reference samples.
