Nuclear methods for trace element determination in fossil fuels: Coals, fuel oils, and gas oils

Determination of Mercury in Coal by Isotope Dilution Cold-Vapor Generation Inductively Coupled Plasma Mass Spectrometry

“…Several analytical techniques have been used for the determination of mercury in coal. The most commonly used technique is cold-vapor atomic absorption spectrometry (CVAAS). − Other techniques including atomic fluorescence spectrometry (AFS), − radiochemical neutron activation analysis (RNAA), − and inductively coupled plasma mass spectrometry (ICPMS) 6,19 have also been used. The removal of mercury from the coal matrix by mild pyrolysis combined with a variety of detection methods has also been employed. ,,,− Evans et al .…”

Wear Metal Analysis of Oils

“…The drawbacks of this technique are long analyzing times and expensive equipment including radioactive material (76). NAA was used for determining metals in oils in 1970 by Flaherty Other application areas of NAA related to oils are studies on various fuels, such as coal, fuel oil, gas oil and oil shales (142,143). NAA can also be used to determine elements otherwise difficult to analyze in oils, such as oxygen and nitrogen (144,145).…”

Applicability and Limits of Instrumental Neutron Activation Analysis: State of the Art in the Year 2000

“…Environmental samples (coal, oil, ash, dust, soil, sludge, sediment) are frequently characterized by INAA (32,34,36,37,51), which can be directly applied even to samples of kilogram size (52,53). The aim of the analyses is often pollution control, which requires monitoring of a wide variety of pollutants, as the cross-influence of many elements is well recognized.…”
