ОПРЕДЕЛЕНИЕ ПРИМЕСЕЙ В ОСОБО ЧИСТЫХ НАНОПОРОШКАХ ОКСИДА ИТТРИЯ, ЛЕГИРОВАННОГО НЕОДИМОМ, МЕТОДОМ АТОМНО-ЭМИССИОННОЙ СПЕКТРОМЕТРИИ С ИНДУКТИВНО СВЯЗАННОЙ ПЛАЗМОЙ

The technique of inductively coupled plasma atomic-emission spectrometry determination of Al, Ba, Be, Ca, Cd, Co, Cr, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Sb, V and Zn in neodymium doped yttrium oxide nanopowders was developed. The limits of quantitation raged in diapason 10 -5 -10 -4 % mass. Matrix effects were minimized using the standards and blank solutions with the same content of matrix (≈ 1 %mass.) as the samples solutions.
