Determination Of Impurities

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, l, 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%.

In contrast to the adjustment of single plates a block adjustment is a simultaneous determination of all unknowns associated with many overlapping plates (star positions and plate constants etc. ) by one large adjustment. This plate overlap technique was introduced by Eichhorn and reviewed by Googe et. al. The author now has developed a set of computer programmes which allows the adjustment of any set of contemporaneous overlapping plates. There is in principle no limit for the number of plates, the number of stars, the number of individual plate constants for each plate, and for the overlapping factor.
