The electrolytic deposition of ZrO₂ film on ITO glass applied in the detection of rutin

Abstract

Zirconium dioxide (ZrO₂) nanoparticles is deposited on ITO substrates to improve the optical selectivity of ITO glass and applied as a sensor for the detection of rutin. The deposition of ZrO₂ nanoparticles was done by the electrochemical method in Zr(NO₃)₂ aqueous solution at a current density of 11.1 mA/cm². The mechanism of electrochemical deposition of ZrO₂ on ITO glass and the selectivity reaction of rutin with ZrO₂ are studied in this work. It demonstrated the compatibility for establishing specific interaction between ZrO₂ and rutin and can be used as a suitable surface for pursuing experiments in selective detection of rutin. The developed ZrO₂/ITO sensor was applied in the measurement of different rutin concentrations in solution with a good linearity (ranging from 0.3 mM to 1.5 mM). A less sophisticated, cheaper and highly sensitive novel ZrO₂/ITO sensor for the detection of rutin has successfully been developed for future applications.
