چکیده
|
The poly (fast sulfone black f) film was synthesized on the surface of graphitepencil electrode by cyclic voltammetric method. the synthesized polymer film coatedelectrode exhibit excellent electrocatalytic activity towards the detection of dopamine at 7.0ph. the scan rate effect was found to be diffusion controlled electrode process. theconcentration effect of dopamine was linear with current. the redox peak potentials ofdopamine were depend on ph. this polymer film coated electrode was very good atsimultaneous study of dopamine in presence of high concentrated uric acid. the separatedpeak potential of da-ua was 150 mv by cyclic voltammetric technique.
