The paper considers the applied optical spectroscopy methods application in the defluorinated phosphate production, controlling the technological process task. The emission spectral analysis using the method possibilities to control the charge hydrothermal acid processing process, which takes place in special furnaces with natural gas burning and a temperature of 1340 – 1400°C, have been studied. Experiments have been carried out in production conditions, and the radiation spectral characteristics study results from the furnace during the defluorination technological process are presented. It is shown that, by measuring individual spectral lines, it is possible to provide an automatic control mode for the defluorination technological process in the furnace burner controlling the combustion mode terms without the need for visual observation by the operator to ensure a better product yield. The work second part is devoted to the defluorinated phosphate chemical composition study by the laser-spark emission spectrometry method (LIBS). The LIBS method application for the defluorinated phosphate chemical composition analysis is proposed, which allows the production process parameters real-time control. The plasma spectra measurement and interpretation results from the ready-made defluorinated phosphate sample, obtained using the LIBS method, are presented.
