Abstract
The present work analyzed the electrochemical activity of certain amino acids on the modified carbon electrode as-prepared, such as glycine, threonine and aspartic acid. The electrochemical methods used to investigate surface electrode behavior through amino acid molecules at a fixed concentration and temperature of 298.15 K in the perchloric acid electrolyte solution. The findings showed that the surface electrode was ideal for the analysis of glycine, threonine, and aspartic acid molecules. Aspartic acid showed electrochemical activity by voltage and polarization resistance to 0.533 mV and 9.557 ohms, respectively. In addition, the FE-SEM images showed the thin film layer on the surface electrode from the amino acid molecules in different shapes and dense aggregations, more with aspartic acid under optimum experimental conditions.
