dc.description.abstractIn this study, multi-wall carbon nanotubes (MWCNTs) immobilized on carbon paste electrode (CPE) was employed for the amperometric detection of ascorbic acid (AA). The influence of pH on the electrocatalytic effect of MWCNTs/CPE towards the oxidation of AA was studied; the effect of the potential applied and the stirring speed for amperometric detection of AA was investigated. The calibration curve was obtained for AA concentrations in a range of 1-100 μM. The detection limit for the method proposed was found to be 0.1 μM in the amperometric mode.eng
