Judging from the closeness of ionic radii of ceric and thorium ions, a method is proposed for the concentration of traces of thorium by coprecipitation with ceric iodate. By means of Th234 as a tracer and photometric determination with arsenazo Ⅰ, it is shown that quantitative recovery of thorium can be achieved.
