A new kinetic method is described for the determination of ultramicro amounts of Cu(II) based on its catalytic effect on the oxidation of trisodium-2-hydro- xy-1-(4-sulphonato-1-naphthylazo)naphthalene-6,8-disulphonato (red artificial color PONCEAU 4R) by hydrogen peroxide in borate buffer (B.B.) The detection limit given by Perez-Bendito is 0.8 ng/cm 3 , but the detection limit that we experimentaly deter- mined is 3.8 ng/cm 3 . The relative error ranges between 7.77 and 2.09 % for the concen- tration interval 3.8 to 50.1 ng/cm 3 . Kinetic equations are proposed for the investigated process. The effects of certain foreign ions upon the reaction rate were determined for an assessment of the selectivity of the method. The method was applied for the determina- tion of Cu(II) ions in samples of alloy.
