Activation analysis application to vanadium concentration in crude oils, in commercial petroleum derivatives, in natural water and in aerosols

Creators

Description

Instrumental neutron activation analysis has been applied to the determination of V concentrations in crude oils, in commercial petroleum derivatives and in aerosols. For 1 min. irradiations in a thermal neutron flux of 1012n.cm-2s-1 and measurements performed with a Ge(Li) well detector, the detection limit is 2x10-3 ppm. The determination of inorganic V concentration in natural water after preconcentration by ions exchangers is obtained with a detection limit equal to 10-4 ppm

Abstract (French)

L'analyse par activation dans un reacteur nucleaire de faible puissance (100 KW) permet un dosage rapide et non destructif du vanadium. La sensibilite limite depend essentiellement de la teneur des autres elements activables presents dans l'echantillon. La methode a ete appliquee aux petroles bruts et a leurs derives. L'analyse des eaux naturelles est possible apres une preconcentration du vanadium inorganique a l'aide de resines echangeuses d'ions. La limite de detection est de 10-4 ppm
