| Description | Journal: Iop Conference Series: Materials Science and Engineering A multi-wall carbon nanotubes/Chitosan electrochemical sensor had been fabricated by dropping CHS/MWNT solution directly onto the GC surface. The sensor was charactered by cyclic voltammetry and AC impedance with $K_{3}Fe(CN)_{6}$ as a electrochemical probe; Cyclic voltammograms(CV) and electrochemical impedance spectroscopy(EIS) indicated that the active area and electrochemical behavior of the sensor increased and improved significantly after the electrode was modified by carbon nanotubes dispersed by the chitosan. The sensor showed good electrocatalytic activity of $K_{3}Fe(CN)_{6}$. Also, from the cyclic voltammograms, we can see the process was diffusion controlled on the bare electrode and kinetics and diffusion controlled on the modified electrode. Finally $Cu^{2+}$ responsed sensitively at the sensor which supplied a new method for the detection of $Cu^{2+}$. |
