Abstract :
The poly (fast sulfone black f) film was synthesized on the surface of graphite pencil electrode by cyclic voltammetric method. The synthesized polymer film coated electrode exhibit excellent electrocatalytic activity towards the detection of dopamine at 7.0 pH. The scan rate effect was found to be diffusion controlled electrode process. The concentration effect of dopamine was linear with current. The redox peak potentials of dopamine were depend on pH. This polymer film coated electrode was very good at simultaneous study of dopamine in presence of high concentrated uric acid. The separated peak potential of DA-UA was 150 mV by cyclic voltammetric technique.
