Influence of matrix on atomic absorption determination of elements as
well as influence of Ba, Fe, Ni, Co and Sn on determination of Bi, Ca,
Sr and Cu have been studied. The results were used to develop methods
of determining of Ba, Fe, Ni, Co and Sn in Bi - Sr - Ca - Cu - O. The
relative standard deviation was obtained to be less-than-or-equal-to
0,01 for optimum amounts of elements.
