FIELD: chemistry.
SUBSTANCE: method of determining calcium ascorbate in biologically active additives includes a sample preparation step and voltammetric determination. The invention involves conducting anodic voltammetry on a glassy-carbon indicator electrode at potential of +0.32 V relative a saturated silver chloride electrode on a background of 0.1 mol/dm3 potassium chloride, with a direct current form of potential sweep at a rate of 30 mV/s with the region of the determined content of calcium ascorbate from 1.5·10-5 to 6.7·10-4 mol/dm3.
EFFECT: efficient sensitive and rapid determination of calcium ascorbate in biologically active additives by voltammetry.
