Direct determination of organic and inorganic oxygen in coals from the Argonne Premium sample program by solid sampling electrothermal vaporization inductively coupled plasma optical emission spectrometry
2017, FuelCitation Excerpt :Unfortunately, analytical errors in direct determination and large weight changes in the mineral matter (MM) during high-temperature ashing are reflected in this oxygen value. In consequence, the calculated ODiff is an uncertain value and can sometimes be a negative value using the Standard Method for the Ultimate Analysis of Coal and Coke [7,10]. The complexities of analyzing the organic substances of coals have been discussed in some detail by Given and Yarzab [6].
Determination of organic oxygen in petroleum cokes and coals
2016, Microchemical JournalCitation Excerpt :About the analysis of the organic oxygen in coals, different papers have been found where different techniques of quantification have been used. The determination of the total organic oxygen has been carried out by thermogravimetry Fourier transform infrared spectroscopy (TG-FTIR), fast neutron activation analysis (FNAA), or pyrolysis–gas chromatography by different authors [3,14–18]. Others use techniques such as the acetylation–hydrolysis and ion-exchange and titration methods, and solid-state C NMR measurement [19], or XPS [1] to analyse the distribution of oxygen-functional groups in coals.
