Vanadium determination in pretoleum by neutron activation analysis

Abstract:

[en] The vanadium concentration in an Peruvian petroleum sample is determined by neutron activation analysis. The samples were irradiated for 20 minutes with a flux of thermal neutrons of 1.75 x 10 7 n/cm 2-s in a subcritical assembly. The activity of the created samples decreases to half 15 minutes after the irradiation. The result is 28.3+-0.8 ppm with a typical deviation of 2.8%. The detection limit of this method is 4 ppm
