Screen-Printed Gold Electrode Functionalized with Deferoxamine for Iron(III) Detection

Deferoxamine (DFO), a hydroxamic siderophore with high affinity for Fe(III), is immobilized as functionalized self-assembled monolayer of thiol (SAM) on the gold surface screen-printed cell to develop voltammetric sensor iron(III). The working electrode was characterized, before and after functionalization, by determining properties such area double-layer capacitance. Fe(III) detection performed DPV analysis preconcentration cation at open circuit potential in solution pH = 1 two minutes. method applied iron(III) quantification water samples giving promising results.
