Determination of carbendazim with multiwalled carbon nanotubes-polymeric methyl red film modified electrode
چکیده انگلیسی

Multiwalled carbon nanotubes-polymeric methyl red film modified electrode (MWNT-PMRE) was made. The electrochemical behavior of carbendazim on modified electrode was studied with Cyclic Voltammetry, Linear Sweep Voltammetry, Stable Polarization Method and Chronocoulometry. The results indicated that the electrical oxidation of carbendazim on MWNT-PMRE in H2SO4 supporting electrolyte with concentration of 0.6 mol/L was irreversible and was mainly controlled by diffusion. Some parameters of the electrochemical process were evaluated. The impacts of experiment conditions on the electrochemical behavior of carbendazim were studied. A good linearity relationship between peak current and concentration of carbendazim in the range of 2.0 × 10−7–1.0 × 10−5 mol/L was found, of which the equation was Ip(A) = −1.149 × 10−5 − 2.301c (mol/L), the correlative coefficient R = −0.9953 and detection limit was 9.0 × 10−9 mol/L. The recovery was between 90.3% and 94.7%.
