Abstract : By means of electropolymerization process, a simple as well as proficient electrochemical sensor was developed for electrochemical resolution of tryptamine. The morphology and electrochemistry of thus fabricated poly (O-Phenylene diamine) reformed pencil graphite is evaluated thoroughly by FESEM along with DPV and CV respectively. Under experimental settings, finely resolved irreversible electro-oxidation peak at potential +0.594 V obtained for tryptamine on the altered electrode surface with phosphate buffer of pH 9 as supporting electrolyte. The oxidation peak current and tryptamine concentration are observed to possess linearity in the range of 0.4 M to 117 M with R2 = 0.99. Additionally the limit of detection (LOD) for tryptamine quantification is found as 0.2 M. The sensor exhibited superior analytical properties such as high reproducibility, repeatability and anti-interference capability. The practical efficiency of fabricated sensor tested successfully in cheese obtained from milk.
