FIELD: chemistry.
SUBSTANCE: method of spectrophotometric determining lactic acid includes adding the test solution to a solution of iron chloride (III) taken at the concentration of 0.1-0.3%, measuring the optical density of the resulting solution at the wavelength of 380-405 nm, and quantifying the concentration of lactate in the initial solution by using a calibration chart.
EFFECT: improving the accuracy.
