Simple and Sensitive Electrochemical Determination of L-Tryptophan at Electrochemically Activated Glassy Carbon Electrode [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2023 Herein, we reported an Activated Glassy Carbon Electrode (AGCE) for the detection of L-tryptophan (Trp). AGCE was made by successive cyclic voltammetric potential scanning of glassy carbon electrode (GCE) from -1.5 V to 2.5 V in 0.1 M pH 7.0 phosphate ...
