Polarographic Catalytic Properties of Cobalt-nitrohydroxylamine Complex

Abstract

THE polarographic catalytic waves, observed by Brdička¹ in the complexes of cobalt or nickel solutions, are considered to be characteristic of organic molecules containing many active groups. It is accepted, in general, that the —SH group is the most specific for the catalytic process in a cobalt-containing medium, but there are also many other substances which do not contain sulphur in their molecular structure but which form catalytic waves: uric acid^2,3, certain amino-acids³ as histidine or lysine, glycerinaldehyde, dihydroxylacetone⁴ and also ethylenediamine⁵.
