The electrode was fabricated by electropolymerization of 6-phenyl-1,3,5-triazine-2,4-diamine as a thin film on the surface of unmodified carbon paste electrode (UCPE) by using cyclic voltammetry. Superficial morphology of UCPE and improved electrode was traced by scanning electron microscopy (SEM). The constructed improved electrode shows admirable electrocatalytic movement for the analysis of dopamine (DA) and uric acid (UA) in 0.2 M phosphate buffer (PBS of pH7.4), which is attributed to increased active surface area. The fabricated electrode process was found to be diffusion controlled and it shows linear range from 10 to 90 μM for DA and 10 to 70 μM for UA and lower limit of detection (LOD) for DA and UA are established at 0.25 and 0.37 μM separately. The fabricated electrode was applied in analytical application in dopamine injection samples.
