A Novel Electrochemical Nanosensor for Voltammetric Determination of Isoproterenol

A new isoproterenol electrochemical nano sensor was fabricated using a acarbon paste electrode modified with ionic liquid (n-hexyl-3-methylimidazolium hexafluoro phosphate) and magnetic core-shell nanoparticles (MCSILCPE). The electrochemical study of the modified electrode, as well as its efficiency for oxidation of isoproterenol, is described. Differential pulse voltammetry (DPV) exhibits a linear dynamic range from 1.0×10-6 to 7.0×10−4 M isoproterenol. The limit of detection was equal to 6.3×10-7 M. The electrode was also employed to determination of isoproterenol in real samples.
