FIELD: electroanalytical chemistry.
SUBSTANCE: enantioselective voltammetric sensor based on a paste electrode of graphitized thermal soot Carboblack C with a chiral modifier – carbon nanotubes CNT and homochiral zeolite MFI (MFI-CNT), taken in the ratio MFI@GPE : CNT 1 mass fraction of MFI@GPE per 1 mass fraction of CNT.
EFFECT: invention enables to create a rapid, cheap, stable and highly sensitive enantioselective voltammetric sensor for determination of enantiomeric purity of biologically active additive "tryptophan" in model solutions, tabletted forms and biological fluids using differential pulse voltammetry.
