EXAMINATION OF DISINFECTANTS USING AN AUTOMATED SPECTROMETER OPERATING IN THE VISIBLE RANGE OF THE SPECTRUM

The paper highlights a modern spectral device for measuring the optical parameters of solid-state materials in liquid-phase. The development of these devices is promising for optical instrumentation and science in general, since these devices are informative, highly accurate and provide reliable information. In the paper the appearance, block diagram and lighting system of the spectrometer are presented. The spectral dependences of the transmission on the wavelength in the visible range of the spectrum for disinfectants Like, Grand, Aqualite (1% solutions) are obtained. For the analysis of the studied substances, specialized cuvettes with a working length from 0.1 to 0.5 mm and leucosapfir optical pads were used. The cuvettes were 0.05 mm thick. The spectrometer provided measurement of the transmission of disinfectants in the wavelength range of 380–760 nm with an error not worse than ΔТ ≤ 2%.
