Abstract

A direct carrier distillation procedure for the determination of a wide range of impurities in uranium tetrafluoride is described. The method is based on the use of lead chloride as carrier with yttrium oxide to suppress uranium spectral interference. A deep crater electrode further aids in the reduction of spectral interference. Germanium and cobalt are used as internal standards. The method has been adopted for the simultaneous determination of Ag, Al, B, Cd, Cr, Cu, Fe, Mg, Mn, Mo, Na, Ni, Si, Sn, Ti, V, and Zn with detection limits in the range 0.1 to 20 ppm and coefficients of variation ranging from 4 to 15%.
