Abstract

A method of instrumental neutron activation analysis (INAA) is developed for the determination of platinum by the ¹⁹⁹Au daughter of ¹⁹⁹Pt in the presence of the spectral interference from the ⁴⁷Sc daughter of ⁴⁷Ca. The contributions of the Pt and Ca signals to the integral 157-161 keV peak were separated by calculating the number of disintegrations due to the ⁴⁷Sc from the signal of her parent ⁴⁷Ca at 1297.1 keV γ-ray. The method was used to calculate the trace concentrations of Pt in air samples, collected on filters.
