Abstract :
An ionic liquid (n-hexyl-3-methylimidazolium hexafluoro phosphate)– ZnIn2S4 nanoparticles modified carbon paste electrode (ZISILCPE) was used as a fast and sensitive tool for the investigation of the electrochemical oxidation of penicillamine using voltammetry. The modified electrode offers a considerable improvement in voltammetric sensitivity toward penicillamine, compared to the bare electrode. Using differential pulse voltammetry (DPV), the electrocatalytic oxidation peak current of penicillamine shows a linear calibration curve in the range of 5.0×10-7 to 8.0×10−5 M penicillamine. The limit of detection was equal to 3.0×10-7 M. The electrode was also employed to determination of penicillamine in real samples
