A novel net analyte signal standard addition method (NASSAM) is presented for the simultaneous determination of Cd 2+ and Ni 2+ in their mixture by differential pulse polarography. The method combines the advantages of the standard addition method with the net analyte signal concept, which enables the extraction of information concerning a certain analyte from voltammo- grams of multi-component mixtures. This method has some advantages, such as: the use of a full voltammogram, realization in a single step, therefore it does not require calibration and prediction steps and only a few measurements are required for the determination. The simultaneous determination of Cd 2+ and Ni 2+ was performed in Britton-Robinson buffer (pH 2.87) and 0.40 M potas-
