Three new modified electrodes based on a well‐characterized Al(III)‐Dicloxacillin complex (Dicloxacillin: penicillin antibiotic) in the form of carbon‐paste, PVC and coated graphite were fabricated and investigated for determination of Al(III) ions in multivitamin syrup, tap water and soda cans. The developed sensors showed excellent sensitives to Al(III) ions with slopes in the range of 16.77–20.00 mV/concentration decade and detection limits of 4.04×10 −4 –3.16×10 −7 mol L −1 as well as fast response time of 10–20 s. The electrodes were effectively applied as indicators in the potentiometric titration of Al(III) with disodium hydrogen phosphate.
