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 x 10(-7) mol L(-1). The constructed electrode showed excellent reproducibility and stability. Actual water samples were analyzed and satisfactory result was obtained.
