title: [Polarographic method of studying natural cobalamins in mixtures].
abstract: By means of polarography and tree-angle scan voltammetry, AdoCbl, MeCbl and OH-Cbl were studied in mixtures and separately. The possibility to obtain a polarographic scope of quality for each of the natural cobalamins studied was shown. The ability of cobalamins to be adsorbed on a mercury electrode enables to increase the sensitivity of the method by conducting the accumulative adsorption from solutions with the concentration up to 1 microgram/ml.
