Sa. Wilson et al., DETERMINATION OF 32 MAJOR AND TRACE-ELEMENTS OF 3 NIST SOIL SRMS USING ICP-AES AND WDXRF, Geostandards newsletter, 18(1), 1994, pp. 85-89
The National Institute for Standards and Technology (NIST) has recentl
y released three soil standard reference materials that are uncontamin
ated (SRM 2709), moderately contaminated (SRM 2711), and highly contam
inated (SRM 2710) with metals. The SRMs were analyzed at the U.S. Geol
ogical Survey (USGS) for thirty two major, minor and trace elements us
ing a combination of wavelength dispersive X-ray fluorescence spectros
copy (WDXRF) and inductively coupled plasma atomic emission spectrosco
py (ICP-AES). Good agreement is observed between NIST certified values
and USGS results. The wide concentration ranges for most transition m
etals should make these SRMs useful in assessing the accuracy of metho
ds used in geochemical exploration and environmental studies.
