; ;
Sorption properties of inorganic ion exchangers have been investigated for use in radiochemical separation of elements in geological samples subjected to neutron activation analysis. Samples were allowed to decay for two weeks, dissolved in hydrofluoric acid, and saturated boric acid was added to dissolve any fluoride complexes. Samples were placed onto the COX column and eluted with nitric acid. Retained on the column were scandium 46, zirconium 95, cesium 141, hafnium 181, lanthanum 140, samarium 153, europium 152-154, terbium 160, ytterbium 169, lutetium 177m, prtactinium 233. Present in the eluant were chromium 51, manganese 54, iron 59, cobalt 60, zinc 65, rubidium 81, niobium 95, barium 131, cesium 134, tantalum 182. 1 figure.
