Electrochemical determination of L-tryptophan in food samples on graphite electrode prepared from waste batteries

Zaklina Z. Tasic et al.

Summary: The research aimed to develop a cheap and non-toxic electrochemical sensor for determining a target analyte and reducing electronic waste. The sensor was prepared using a graphite rod from zinc-carbon batteries and was used to detect L-tryptophan in a Britton-Robinson buffer solution. Two electrochemical methods, differential pulse voltammetry and cyclic voltammetry, were employed in the experiment. The pH value of the support solution, scan rate, and L-tryptophan concentration were found to affect the current response. The oxidation of L-tryptophan was determined to be an irreversible two-electron/two-proton reaction controlled by a mixture of adsorption and diffusion.
