ANALYTICAL METHOD FOR THE DETERMINATION OF NIOBIUM-95 IN VEGETATION, SEAWEED, FISH-FLESH AND NATURAL WATERS
Methods were developed for the determination of Nb/sup 85/ in vegetation, seaweed, fish flesh and natural waters. Samples of vegetation, seaweed, and fish flesh were ignited and the residues were leached with HNO/sub 3/ and HCl in the presence of Nb and Zr carriers. Lanthanides were removed as fluorides. The Nb was precipitated with NH/sub 4/OH. The precipitate was dissolved in a mixture of oxalic and nitric acids and the Nb was precipitated as metaniobic acid. The Nb was further purified, mounted on a counting tray, and the gamma activity determined. From natural waters, the Nb/sup 95/ and its carrier were co-precipitated on larger amounts of Fe as hydroxides. After dissolution in HNO/sub 3/, the radiochemical purification was continued by the process used for the seaweed, fish flesh, and vegetation. (M.C.G.)
