We report a sensitive electrochemical voltammetric method for analysing Iron (II) and copper (II) using an organic molecule (2-Chloroquinoline-3-Carbaldehyde), noted later (MO), as modifier of Natural Phosphate paste Electrode (MO-NPE). The analytical performance of the MO-CPE sensor that is designed for the detection of metals was studied. Organic compound plays an important role in the complexation of metal ions because of their good and high response to these ions. The modified electrode MO-CPE was used for the voltammetric determination, respectively, of iron and copper ions (square wave voltammetry). Na2SO4 solution 0.1 mol/1 was used as the support electrolyte. Using optimal parameters, calibration graph is linear for 5 min of pre-concentration time with the correct detection limit about 1 × 10-8 mol/L. These results indicate that the developed method is simple, with high stability and sensitivity for the determination of low concentration of Fe (II) and Cu (II).
