Electrochemical Sensor for Determination of Fenitrothion at Multi-wall Carbon Nanotubes Modified Glassy Carbon Electrode
A sensor, based on multi-wall carbon nanotubes modified glassy carbon electrode (MWCNT/GCE), was developed for determination of fenitrothion. Determining the surface area of MWCNT/GCE showed that this surface is three times more active than that of a glassy carbon electrode. The experimental parameters, such as the amount of MWCNTs, pH of the fenitrothion solution, preconcentration potential an...
متن کاملAdsorptive Behavior and Voltammetric Determination of Hydralazine Hydrochloride at A Glassy Carbon Electrode Modified with Multiwalled Carbon Nanotubes
An electroanalytical method has been introduced for highly sensitive determination of hydralazine hydrochloride (Hy-HCl) based on its oxidation at a glassy carbon electrode modified with multiwalled carbon nanotubes (MWCNT/GCE). Studies showed that the electrochemical oxidation of Hy-HCl was accompanied by adsorption and highly sensitive responses could be achieved by adsorptive stripping volta...

متن کاملVoltammetric determination of tinidazole using a glassy carbon electrode modified with single-wall carbon nanotubes.
An electrochemical method based on a single-wall carbon nanotubes (SWNTs) film-coated glassy carbon electrode (GCE) was described for the determination of tinidazole. In a 0.1 M Britton-Robinson buffer with a pH of 10.0, tinidazole yields a very sensitive and well-defined reduction peak at -0.78 V (vs. SCE) on a SWNTs-modified GCE. Compared with that on a bare GCE, the reduction peak of tinidaz...
متن کاملElectrochemical behavior and voltammetric determination of 2,4,6-triaminopyrimidine at glassy carbon electrode modified with multi-walled carbon nanotubes/nafion.
A multi-wall carbon nanotubes (MWCNTs) composite with Nafion was modified on a glass carbon electrode. The modified electrode was then used as a voltammetric sensor in detecting 2,4,6-triaminopyrimidine (TAP). The surface morphology of the Nafion/MWCNTs composite film was characterized by atomic force microscopy (AFM), and the electrochemical behavior of TAP at this sensor was investigated in d...
