dc.description.abstractA novel composite obtained from reaction of zirconium (IV) phosphated (ZrP) with Ag+ and subsequent interaction of potassium hexacyanoferrate (III) (ZrPAgH) was prepared and characterized by infrared spectroscopy (FTIR) and cyclic voltammetry. The graphite paste electrode modified with ZrPAgH exhibited a cyclic voltammogram with a redox couple with midpoint potential E-theta' = 0.70 V (vs Ag/AgCl(sat.)), attributed to the Ag-I-CN-Fe-II/Ag-I-CN-Fe-III process (40% w/w; KNO3 1.0 mol L-1; v = 20 mV s(-1)). The graphite paste electrode modified with ZrPAgH can be used in the electrocatalytic oxidation of L-cysteine in a linear range from 1.0x10(-5) mol L-1 to 8.0x10(-5) mol L-1 (R = 0.995) with detection limit of 1.02x10(-5) mol L-1 and amperometric sensitivity of 2.40 mA/mol L-1.en
