TRACE METAL ANALYSIS OF OILS AND ASPHALTS BY NEUTRON ACTIVATION TECHNIQUES,
Abstract
The neutron activation method of analysis, and in particular the systematic procedure proposed by the authors, offers the possibility of trace-metal determinations on crude oils and related substances, even when only very small samples are available for the analysis. The excellent accuracy and sensitivity of the method alloy the determination of smaller amounts of metals in petroleum than can be measured by ordinary spectrographic techniques. It may thus be possible to investigate the geochemical significance of trace metals other than vanadium and nickel, and which ordinarily are present in petroleum only in very minute concentrations. Vanadium and nickel can be conveniently determined by a very precise simplified neutron activation technique, without the need for ashing the sample. This procedure, therefore, eliminates potential losses and the consequent low values. (Author)
