A new voltammetric sensor for the detection of ethylmalto was developed, based on the carbon nanotube ( CNT)/ITO modified electrode which allows for lower background current and more reproducible responses. The resulting sensor exhibits excellent redox activity towards ethylmalto. CNT/ITO electrodes were obtained by electrophoretic deposition (EPD) method .Further differential pulse voltammetry (DPV) experiments demonstrate that the oxidative peaks increased linearly with ethylmalto concentration in the range of 2.0×10-6 to 8.0×10-5 mol L-1 with a linear equation of ip= 0.3428 + 0.7132C and coefficient of 0.994.
