✦ Synopsis

A convenient electrochemical deposition method to prepare nanogold/glassy carbon modified electrode (nano-Au/ GCE) is adopted. In 0.1 mol/L HAc-NaAc buffer solution (pH 4.61), the nano-Au/GCE shows an excellent electrocatalytical behavior for the redox of dihydroxybenzene. A simple, rapid and highly selective voltammetry for simultaneous determination of dihydroxybenzene isomers, hydroquinone, catechol, and resorcinol, is developed using the nano-Au/GCE. This method has been applied to the direct determination of the three dihydroxybenzene isomers in artificial wastewater.
