| Abstract: | Summary A method for the simultaneous determination of arsenic, selenium and antimony in biological samples by means of wavelength dispersive X-ray fluorescence spectrometry (XRFS) is described. The method entails a procedure for the destruction of the biological material, followed by the simultaneous generation and accumulation of the hydrides of the elements of interest onto an impregnated cellulose filter, and measurement by XRFS. |
