Radiochemical separations in molten salts. Determination of carbon in metals by photon activation

A systematic study of radiochemical separations of carbon in molten salts was achieved. It combined forecasting of salt mixtures from literature data and experimental work The basic three mixtures of molten salts which were studied, are the following: Pb₃O₄−B₂O₃, NaOH−NaNO₃ and H₂SO₄−KIO₄ with some additions of complexing agents Selected procedures for the determination of carbon by photon activation were issued for the following samples: Ag, Al, Cr, Fe, Mg, Mo, Ni, Si, Ti, W, Zn, Zr, AlMg, AgZn and ZnMgTe. The detection limit for carbon was 10⁻⁸ g and the accuracy from 5 to 10%. Applications to solid state science are given.
