    Abstract

    The electrochemical behaviour of a glassy carbon (GC) electrode modified with MWCNTs was investigated and characterised using K3[Fe(CN)6] as a probe. An increase in the electroactive surface area and the rate of electron transfer was observed on sonication of the MWCNTs prior to casting at the GC electrode. The modified electrode was also used in the detection of Cr(VI) in both pH 5.0 and pH 2.0 aqueous solutions. Better detection limits were obtained in the acidic solution.
