Spectrographic determination of impurities in uranium tetrafluoride
Description
A carrier distillation method for the determination of Ag, Al, As, B, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, and Si in uranium tetrafluoride was develop ped. the previous addition of 25% Y23 prevents the excitation of uranium by conversion of the volatile UF4 into U308 during the arc discharge. NaCl or Ga203, containing Ge and V as internal standards, are used as carriers, and samples are arced in 10 Amp. d.c. arc in a graphite anode cup. 7 mm diameter, 10 mm deep, being the weight of charge 300 mg.
