Nguyen, Tong Hoang Oanh published the artcileStudy on influence of 2-nitrodiphenylamine and some different diphenylamine nitro derivatives on polarographic catalytic current in solution containing Co2+-NO2–, Formula: C12H9N3O4, the publication is Tap Chi Phan Tich Hoa, Ly Va Sinh Hoc (2002), 7(2), 57-61, database is CAplus.
The effect of nitro-substituted diphenylamine derivatives including 2-nitrodiphenylamine (2-NDPA), 4,4′-dinitrodiphenylamine (4,4′-DNDPA), and 2,4,4′-trinitrodiphenylamine (2,4,4′-TNDPA) on polarog. catalytic current in solution containing Co2+-NO2– was studied by cathodic adsorption stripping voltammetric method. All the nitro-substituted diphenylamines showed catalytic activation effect in solution containing Co2+-NO2–. The capability of these diphenylamine derivatives to form intermediate complexes that have catalytic activity and electrochem. adsorption between ions Co2+-NO2– ions with organic ligands was dependent on the type of the diphenylamine compounds
