Measurement of barium in petroleum products using 2.8-MeV activation analysis
An evaluation was made of the feasibility of using 2.6-MeV neutron activation analysis for the measurement of barium in a commercially produced diesel fuel anti-smoke additive. Neutron production was achieved by means of a Cockroft-Walton accelerator, equipped with a deuterium target. Two methods of monitoring the neutron production were investigated. One method made use of a BF/ sub 3/ detector located a few feet from the accelerator target, while the other involved simultaneous activation of gold which was included in the irradiation vial containing the diesel-fuel additive. The gamma spectra from /sup 173m/Ba and /sup 197m/Au produced during the irradiation were recorded by dual Nal(Tl) crystals and a 1024-channel analyzer. The integrated spectra were compared in a manner that allowed a calculation of the precision of the activation analysis method to be made. The precision obtained indicated that 2.8-MeV neutron activation analysis has potential for routine analysis of barium in petroleum additives. (auth)
