Cyclic Voltammetric Investigation of Dopamine at Poly-(Gabapentin)‎ Modified Carbon Paste Electrode

الملخص EN

The poly (gabapentin) film was prepared on the surface of carbon paste electrode by electrochemical method using cyclic voltammetric technique.

The poly (gabapentin) film-modified carbon paste electrode was calibrated with standard potassium ferrocyanide solution in 1 M KCl as a supporting electrolyte.

The prepared poly (gabapentin) film-coated electrode exhibits excellent electrocatalytic activity towards the detection of dopamine at physiological pH.

The scan rate effect was found to be diffusion-controlled electrode process.

The concentration effect of dopamine was studied, and the redox peak potentials of dopamine were dependant on pH.
