Traces of cobalt in biological materials were determined by flow-injection flame atomic absorption spectrometry. The analyte was preconcentrated and separated from the bulk of the matrix by on-line ion-pair adsorption of the cobalt-nitroso-R salt complex in the presence of tetrabutylammonium bromide
