Abstract

In atomic absorption spectrometric determinations of cobalt(II) and cobalt(III), the interfering effects of different complex-forming substances can be completely eliminated by addition of excess of cyanide. Cyanide has a double role: first, it forms very stable cyano complexes, so that the cobalt species reaching the flame will normally be independent of the original composition of the solution; secondly, the high excess of cyanide produces favourable physical and chemical conditions for cobalt atomization.
