Synthesis, Characterization, and Fabrication of a Salicylaldazine-Modified GC Electrode to Detect Tryptophan in Food Samples: An Analytical Technique Using an Electrochemical Approach.

ABSTRACT: The current investigation attempts to devise a simple and clean method to synthesize salicylaldazine (SA) using a green approach. The prepared compound was characterized using UV-vis, LC-MS, and SEM techniques. The SA was applied to a glassy carbon electrode (GCE) to obtain modified SA-GCE and used to detect the tryptophan levels in food products such as milk, egg, and chicken as samples. The fabricated electrode demonstrated excellent stability in addition to reproducibility and repeatability of the data performed using voltammetric techniques, viz., cyclic and differential pulse voltammetry. The contributions of various constraints that include concentration effects, pH, in addition to the scan rate have been determined. The detection limit for SA-GCE was 0.065 μM with a linear range fro
