[en] Boron and cadmium impurities in U metal and U3O8 may be determined by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) after their separation from the U matrix by multiple extractions with tri-n-octyl phosphine oxide (TOPO). Useful precision and accuracy were obtained at concentrations of approx. 0.2 μg/g U
