Water analysis via portable X-ray fluorescence spectrometry [PDF]

Journal of Hydrology, 2017
Abstract Rapid, in-situ elemental water analysis would be an invaluable tool in studying polluted and/or salt-impacted waters. Analysis of water salinity has commonly used electrical conductance (EC); however, the identity of the elements responsible for the salinity are not revealed using EC.
