Instrumental Neutron Activation Analysis of Fourteen Carbonate Reference Materials from the NBS and George Frederic Smith and Eleven Industrial Geological Samples from the Bureau of Analysed Samples

Abstract

New data are presented for the analysis of the elements: REE, Na20, Fe2O3, Cr, Co, Rb, Cs, Ba, Hf, Ta, Th and Il in twenty-five less well known carbonate and industrial geological reference materials by instrumental neutron activation analysis. The materials include NBS 1c, 15e, 88a and 120b from the National Bureau of Standards, Washington DC; GFS 400-403, 405, 407, 411, 412, 415 and 417 carbonate materials from George Fredrick Smith, Columbus, Ohio and BCS 267, 269, 309, 315, 319, 367, 368, 375, 376, 381 and 382/1 from the Bureau of Analysed Samples, Middles-borough, Cleveland, UK. Particular attention has been given to the correction of interferences due to the fission of uranium in the determination of the elements La, Ce, Nd and Zr.
