Description
Summary:Efficient highly sensitive methods are proposed for the direct determination of nonmetallic impurities in uranium materials by inductively coupled plasma mass spectrometry (ICP-MS). The possibility for the elimination of polyatomic overlap interferences on the signals of 32 S and 35 Cl using high-resolution measurements ( m /Δ m = 4000) was demonstrated. The influence of the operation conditions of the mass spectrometer, such as plasma power and nebulizer gas flow rate, was investigated, and the effect of the uranium matrix on the analytical signal of the isotopes to be determined was studied. The detection limit and lower limit of the analytical range for B, Si, P, S, Cl, and Br in uranium materials were estimated. The developed procedures were certified as standard trade procedures and used at the Urals Electrochemical Integrated Plant for the quality control of uranium materials.
