С. 14-16Abstract: In this study, we created a voltammetric sensor for the simultaneous determination of tryptophan and 5-hydroxytryptophan with an immobilized film of polypholic acid. Polypholic acid film was applied by cyclic voltammetry within the potentials -1V ^ + 1V. Tryptophan and 5-hydroxytryptophan were determined by anode scanning of the potential, the oxidation potential of tryptophan is 0.75 V; the oxidation potential of 5- hydroxytryptophan is 0.40 V. The minimum detection limit for 5-hydroxytryptophan is 1 x 10'8 M; tryptophan - 1 X 10'^ M. The range of determined concentrations is 0.5 x 10'8 - 50.0 x W'8 mol / dm3 for 5-hydroxytryptophan and 0.84 X 10-7 - 38.00 x 10-6 mol / dm3 for tryptophan.
