Multielement neutron activation analysis of bauxites

A technique has been developed of determination of 22 scattered elements (REE, Sr, Zr, Sc, W, Th, U) in boxites using neutron activation analysis of one specimen. Gamma-spectrometric identification of activized elements is carried out after their chromatographic separation into groups. Combination of chromatographic separation with semiconductor gamma-spectrometry increases selectivity, sensitivity and accuracy of analysis
