Resumo: An electroactive and chemically stable composite was obtained from zirconium (IV) isopropoxide (ZrI) and phosphoric acid (ZrP). The ZrP was characterized by techniques such as Fourier transform infrared spectroscopy, C-13 and P-31 nuclear magnetic resonance, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, thermogravimetric analysis, X-ray photoelectron spectroscopy, surface area and porosity and cyclic voltammetry. Voltammetric behaviour of the ZrP was obtained using of a modified graphite paste electrode in a potential range from -0.20 to 1.00V (vs Ag/AgCl). ZrP showed one redox couple with average potential E = 0.30V (vs Ag/AgCl(sat.)) (40% w/w; v=20mV s(-1); KCl; 1.00mol L-1). It was tested on electrocatalytic detection of ascorbic acid using cyclic voltammetry and square wave voltammetry. The modified electrode showed a detection limit of 2.4x10(-5) mol L-1, with relative standard deviation of +/- 3% (n=3) and amperometric sensitivity of 11.7mA/mol L-1 (R=0.999) by using the cyclic voltammetry technique and a detection limit of 1.10x10(-4) mol L-1 with relative standard deviation of +/- 2% (n=3) and amperometric sensitivity of 126.9mA/mol L-1 (R=0.998) by using the square wave voltammetry technique.
