Abstract

An enantioselective voltammetric sensor based on graphitized carbon black paste electrode modified by cyanuric acid for the selective recognition of tyrosine enantiomers was developed. It was possible to increase the reliability of recognition and solve the problem of the proximity of the analytical characteristics of the recorded voltammograms using the principal component analysis and projection to latent structures discriminant analysis.
