| Abstract: | Chitosan,hydroxypropyl chitosan and O-hydroxypropyl-N-octyl chitosan which work as a new carbon nanotube dispersion were employed to prepare new electrochemical sensors by dropping solutions directly on electrodes.Cyclic voltammetry and AC impedance method were employed to characterize the sensors with K3Fe(CN)6 as a chemical probe.Experimental results show that the sensitive redox peak of K3Fe(CN)6 on the modified electrodes appears in cyclic voltammetry,with the peak potential negatively shifting 50 mV,an... |
| Keywords: | chitosan and derivatives of chitosan sensor cyclic voltammetry AC impedance method |
