Description

Two fly ash samples produced by coal burning in thermal power plants were analyzed in order to determine various microelements. The method of thermal neutron activation was used for this purpose. Well determined amounts of samples and adequate standards were prepared for irradiation. The thermal neutron activation was performed at TRIGA ICN- Pitesti reactor in the reflector zone. After activation, the samples were qualitatively and quantitatively measured by gamma spectrometry at IFIN-HH. A measuring chain containing a HPGe detector and the ACCUSPEC-A program provided by Canberra company were used. The following elements were determined: Ca, Na, Sc, K, Co, Fe, Ag, Pt, W. Their concentrations were in the range (10-6 - 50)%. (authors)
