Analysis of platinum for certain elemental imparities by neutron activation.
Silver, ruthenium, cobalt, iron, zinc, cadmium and mercury are determined in platinum by neutron-activation analysis. The scheme developed requires the removal of the platinum matrix by reduction and the sequential separation of the elements by ion-exchange chromatography. The method is suitable for the simultaneous determination (at the ppm level) of these elements in milligram quantities of platinum.
