Abstract

In the refining of precious metals it is desirable to be able
to determine amounts 'of the elements remaining in solution after
various precipitations. Neutron-activation analysis can be used
advantageously in this field, and in the present report the application
of the method for the determination of traces of palladium,
gold and iridium is described. The nuclear reactor BEPO at
Harwell was used as the source of neutrons and each of the three
elements could be determined wHh high sensitivity in a 0.5-ml
aliquot of a sample solution. Results of analyses of microgram and
submicrogram quantities of palladium, gold and iridium in the
solutions under investigation showed good precision.
