Kinetic spectrophotometric determination of Co(II) ion by the oxidation of Ponceau 4R by hydrogen peroxide
A new, sensitive and simple kinetic method has been developed for the determination of traces of Co(II) ions based on their catalytic effect in the oxidation of trisodium-2-hydroxy-1-(4-sulphonato-1-naphthylazo)naphthalene-6,8-disulphonate (red artificial color Ponceau 4R) by hydrogen peroxide in bo...
