| Popis: | A combination of Semi-absolute Fast Neutron Activation Analysis (SFNAA) and Energy Dispersive X-ray Fluorescence (EDXRF) analysis has been employed to determine 35 inorganic elements in coals from four different mines across the minefields of Nigeria. A plot of certified against measured values of elemental constituents in a National Bureau of Standard coal reference material, SRM 1632 a, with a regression coefficient of r=0.894, is used to demonstrate the efficacy of this technique. With a complimentary application of the EDXRF technique, better precision is obtained for short-lived isotopes reducing the need for a more sophisticated transfer system and cyclic activation analysis in the situation under discussion. |
