The method proposed in this paper for determination of
different metallic elements in crude oil-water emulsions
has proved to be reliable. The recovery values obtained for SRMs, addition of elements to samples of Orimulsion
and comparison of some results with X-ray fluorescence
determinations show a deviation lower than + 5%. The
sample preparation method is quite simple and can be
easily handled. Its main drawback is the time required
to prepare the sample, but a number of samples can be
prepared at the same time by one operator.
