energy dispersive x-ray spectrometry

(1986) reporting positive results with energy dispersive X-ray spectrometry, but Landsberg et al.

ASTM E1588-10e1, Standard Guide for GSR analysis by Scanning Electron Microscopy/Energy Dispersive X-ray Spectrometry, American Society for Testing and Materials, West Conshohocken, PA, 2010.

Atomic absorption spectroscopy (AAS) and transmission electron microscopy coupled with energy dispersive X-ray spectrometry were used for elemental and ionic analysis of P, Fe, S, SO4, and PO4 in supernatants and sediments.
