A method is described for the separation of 10 -s g quantities of thorium from solutions of iron meteorites, using 1-(o-arsono-phenyl-azo)-2-naphthol-3 : 6-disulphonic acid as a precipitant and zirconium as a carrier: uranium present has been shown to remain quantitatively in solution. Two methods are described for the recovery of uranium, in a sufficiently pure state for fluorimetry: these are solvent extraction and paper chromatography. A 233 U tracer technique, combined with fluorimetry, has allowed reliable estimates to be made of meteoritic uranium.
