Epithermal neutron activation analysis along with ICP-OES, LA ICP-MS, and XRF were used to determine the elemental composition of coal fly ash from the Malta coal power station in the Mpumalanga province of South Africa. A total of 54 major, trace and rare earth elements were obtained by the four analytical techniques. The results were compared and the discrepancies discussed to show the merits and drawbacks of each of the techniques. It was shown that the elemental content of this particular coal fly ash are of the same order as the NIST standard reference material Coal Fly Ash 1633b.

W celu określenia składu pierwiastkowego popiołów lotnych z elektrowni węglowej Malta w prowincji Mpumalanga w Republice Południowej Afryki wykorzystano epitermalną, neutronową analizę aktywacyjną oraz ICP-OES, LA ICP-MS i XRF. Za pomocą czterech techniki analitycznych oznaczono stężenia 54 głównych i śladowych pierwiastków oraz pierwiastków ziem rzadkich. Wyniki porównano, a także opisano różnice pokazujące zalety oraz wady każdej z wykorzystanych metod. Wykazano, że skład pierwiastkowy popiołu lotnego jest porównywalny ze składem standardowego materiału odniesienia NIST Węgiel Popiół Lotny 1633b.
