<br/><br/> In this work we focused on the fabrication of a new chemically modified  carbon paste electrodes for determination of Fe(II) and Al(III) ions based on  polymer as ionophore. They were described for determination of the ions under  investigation using potentiometric calibration and the experimental parameters  were optimized according to ICH guidelines. The performance of such sensors  in the potentiometric determination of Fe(II) and Al(III) ions in pure and water  samples were compared with those of spectrophotometric and ICP methods. The  surface characterization of the sensors was described using SEM, IR and EDX.  Method validation parameters were carefully studied according to IUPAC  recommendations
