Electrochemical Sensor of Heavy Metals Based on Chelating Compounds

Abstract

The analytical performance of developed organic film screen –printed sensors designed for the detection of metals was evaluated. The modified surface exhibited an affinity to chelating metal ions in solution, forming echnology of Beni Mellal, Morocco complexes. Square wave voltammetry combined with a pre-concentrating process and standard additions were employed for trace analysis. Finally, cyclic voltammetry technique was used to characterize the developed organic film surface behavior in presence of different metals.
