Abstract. The issues of studying the optical properties of aviation technical washing liquids in the ultraviolet wavelength range are considered. Correct identification of cleaning fluids for washing the gas-air path of a gas turbine engine is essential for ensuring flight safety. The method of ultraviolet spectroscopy is presented and the optical scheme of the spectrofluorimetric analyzer is given. The spectral dependences of the absorption coefficient of the studied media mixed with distilled water are measured, and the maximum values of the absorbance of the studied samples in the ultraviolet wavelength range are determined.
Keywords: absorption coefficient, spectrofluorimetric analyzer, cuvette, sample, wavelength, technical detergents
