The determination of trace-element impurities in natural diamonds by instrumental neutron activation analysis



The determination of trace-element impurities in natural diamonds by instrumental neutron activation analysis



Journal of Radioanalytical and Nuclear Chemistry 17(1-2): 195-216



On applique la technique d'analyse par activation neutronique non destructive, utilisant un detecteur Ge(Li) a haute resolution pour determiner des traces d'impuretes dans des diamants. La presence de 40 elements est mise en evidence dans les diamants naturels. On donne des resultats quantitatifs portant sur 13 elements dans 25 echantillons de diamant representatifs d'une meme origine. Un rapport a ete etabli entre la chimie des inclusions et la couleur des diamants d'une part, et les traces des elements trouves d'autre part.
