Abstract: The application of p-aminophenol as a suitable mediator, as a sensitive and selective
voltammetric sensor for the determination of hydrazine using square wave voltammetric
method were described. The modified multiwall carbon nanotubes paste electrode exhibited
a good electrocatalytic activity for the oxidation of hydrazine at pH= 7.0. The catalytic
oxidation peak currents showed a linear dependence of the peaks current to the hydrazine
concentrations in the range of 0.5–175 μmol/L with a correlation coefficient of 0.9975. The ...
