Analysis of Jamaican soils and sediments by energy-dispersive X-ray fluorescence spectrometry
Journal of Radioanalytical and Nuclear Chemistry
Date of Publication
Describes the calibration of a tube excited energy-dispersive x-ray fluorescence spectrometer for routine geochemical analyses of Ca, Ti, V, Cr, Mn, Fe, Cu, Zn, Rb, Sr and Pb in Jamaican soils and sediments. Simple linear and parabolic regression models using scattered radiation and an element as internal standards were applied. The analysis of over 200 samples from a regional soil survey has been used to contribute to a database on the geochemistry of Jamaican soils and sediments. An application example of the Zn distribution map in Jamaican soils is presented.....
