The electrochemical behavior and electrochemical determination of carbamazepine (CBZ) at hydrophobic ionic liquid 1-Benzyl-3-Methylimidazole hexafluorophosphate ([BnMIM]PF6) modified carbon paste electrode ([BnMIM]PF6/CPE) in the presence of sodium dodecyl sulfate (SDS) were investigated. A well-defined and sensitive oxidation peak was observed at [BnMIM]PF6/CPE in the presence of SDS and 0.10 M phosphate buffer solution (pH 6.80). The oxidation peak current of CBZ increased significantly at [BnMIM]PF6/CPE in the presence of SDS compared with that in the absence of SDS at carbon paste electrode. It suggested that both SDS and [BnMIM]PF6/CPE show an obvious enhancing effect on the electrochemical oxidation of CBZ. The electrochemical kinetic parameters for CBZ at [BnMIM]PF6/CPE in aqueous SDS solutions were also determined by Chronocoulometry and Chronoamperometry. Finally, the experimental conditions were optimized, and a new electrochemical method of determination for CBZ had been established. The oxidation peak current was linearly dependent on CBZ concentration in the range of 7.0 μM to 0.7 mM with a detection limit of 0.98 μM (signal to noice ratio, S/N = 3). The relative standard deviation for six determinations of 0.10 mM CBZ was between 1.40 and 2.13%. The proposed method was applied in the determination of CBZ in commercial tablet samples. |
