FIELD: methods of absorption spectroscopy. SUBSTANCE: in compliance with invention concentration is determined by way of simultaneous or time-cyclic measurement of absorption of radiation by analyzed solution on three wavelengths lambda1, lambda2 and lambda3.. lambda1 lies in accordance with procedure in range of wavelengths from 390 to 410 nm, lambda2 from 440 to 450 nm and lambda3 from 500 to 700 nm. EFFECT: enhanced accuracy of determination of concentration of iodine-carrying substances. 5 cl, 5 dwg, 1 tbl
