The adsorption of cobalt(II) was studied on silica gel with chemically bound triphenylphosphonium groups. Cobalt was quantitatively recovered only in the presence of an additional ligand, nitroso-R-salt, in the solution. A sorption–spectrometric procedure was developed for determining cobalt in waters and alloys.
