PHYSICOCHEMICAL PROPERTIES OF SODA INDUSTRY DISTILLATION SOLUTIONS AND STRUCTURAL ANALYSIS OF PRODUCTS SYNTHESIZED IN THE PRESENCE OF SODIUM HYPOCHLORITE

In this study, a secondary product generated during the application of a classical technological process in the calcined soda production unit of JV LLC “Kungrad Soda” was investigated using modern physicochemical analysis methods. The composition and phase state of the distillation liquor were determined by X-ray diffraction (XRD) and X-ray fluorescence (XRF) analyses. The results revealed the predominance of calcium and magnesium compounds in the solution, as well as the presence of chloride and carbonate components. The distillation liquor was subjected to chemical modification with a 16–18 wt.% sodium hypochlorite solution at various reagent ratios, resulting in the synthesis of new inorganic reaction products. The chemical composition and structural characteristics of the obtained products were comprehensively studied using infrared (IR) spectroscopy and X-ray diffraction analysis. The obtained results demonstrate the feasibility of recycling soda industry waste to produce inorganic products and confirm the prospects for developing environmentally sustainable low-waste technologies, as well as the utilization of these wastes as raw materials for chemical industry applications.
