Abstract

The results of the experimental research of the change in the absorption spectra of ascorbic acid solutions with the addition of stabilizer NaHCO₃ have been presented. It was shown that L-ascorbic acid is degraded in an aqueous solution, which causes a change in its absorption spectrum. The use of sodium bicarbonate as a stabilizer did not significantly change the absorption spectrum of chemically pure ascorbic acid in the range of 200-300 nm. The obtained results allow to control the concentration and conditions of application of these stabilizers.
