ABSTRACT
A novel modified electrode was constructed by electropolymerization of bromophenol blue at a multi-walled carbon nanotubes modified glassy carbon electrode. The electrode developed was used for the simultaneous determination of the isomers of dihydroxybenzene in environmental samples using a voltammetry method. There was a linear relationship over the range 10−6–10−4 mol L−1 of hydroquinone, catechol and resorcinol; the detection limits was 3 × 10−7 mol L−1. The constructed electrode showed excellent reproducibility and stability. Actual water samples were analyzed and satisfactory result was obtained.
