| Summary: | The electrochemical sensor for Dopamine (DA) was investigated using poly(amido black) modified carbon paste electrode (MCPE) by the cyclic voltammetric (CV) technique. The film-coated electrode exposed supreme electrocatalytic properties towards electrochemical detection DA and uric acid (UA). The limit of detection (LOD) of DA and UA found to be 2.03 µM and 3.6 µM respectively. Furthermore effectively selective separation of DA and UA in a binary mixture was accomplished. The application of the developed electrode was demonstrated by detecting DA in the injection sample with adequate recoveries. The sensor was stable, sensitive, selective and reproducible. |
