Estudio de la Correlación Entre Áreas Espectrales Obtenidas con la Técnica Gamma Natural y Espectrometría Mössbauer de Carbones

In this work, it intends to establish a possible spectral correlation between both techniques, Natural Gamma and Mossbauer Spectrometry, when they are applied to the study of the mineral matter of the coal (ash); in order to have an available method more reliable in the determination of the content of ash in the coal. We can reach this, in the technical natural gamma, by associating proportionally the spectral areas of soils and coals, with the quantity of matter mineral present in a given sample; and in the Mossbauer spectrometry, we do it, identifying the different iron species that are present in the coal, some of them, are composed of diverse chemical elements as S, Al, Si, K, etc. and potentially they can give outstanding information about the quantity of ash in the sample (in accordance with its corresponding spectral area). After obtaining the respective gamma natural and Mossbauer spectra of 10 different coal samples, to analyze them and to compare their areas with the percentage of ash of each sample (previously well-known for analysis thermo-gravimetric), and also, after to compare them, the best natural gamma-Mossbauer correlation, is observed in the jarosite case, according to the hypothesis for this work; in general the obtained lineal correlation coefficients are in the range since 0.70, until a little more of 0.90.
