Zusammenfassung:	FIELD: analytical methods. ^ SUBSTANCE: method of determining cobalt comprises extracting it from cyanate ion-containing solution with complexing agent and extractant followed by analysis of extract, said extractant and said complexing agent representing a mixture of fusible diantipyrylhexylmethane and benzoic acid taken in molar ratio 1:(0.25/4), whereas extraction is effected at medium acidity expressed as 0.05-3.00 M HCl, after which extract is titrated. ^ EFFECT: increased selectivity and safety of analysis. ^ 1 tbl
