Abstrakt:

Composition-property diagrams of NaBr-Ba(H2PO2)2 -H2O ternary water-salt system, which is contained within A+, B++/ X-, (H2PO2)- // H2O (A+= Na+, Li+, K+, NH4+ etc.); (B++= Ba++, Fe++, Mg++, Cu++, Ni++ etc.); (X- = Cl-, I-, Br- etc.) Na+, Ba++/ Br-, (H2PO2) -//H2O quaternary water-salt system were drawn with the isothermal method. In this study, the phase equilibria of the NaBr -Ba(H2PO2)2- H2O triple system that are included in the quaternary mutual water-salt system containing Na+, Ba+2/Br-, (H2PO2)-//H2O, at 298 K were investigated. The physicochemical properties of the liquid phase, which is in equilibrium with the solid phases of the system, such as density and conductivity were also studied. The system's solubility, density, conductivity, and equilibrium phases were studied, with the use of a special glass container placed in an electro-thermostat. We used titrimetric analysis in analytical chemistry and physicochemical phase diagram techniques to test the developed system. In the ternary water-salt system studied (% mass), an invariant point having a composition of NaBr-46.27%, Ba (H2PO2)2-5.75%, H2O- 47.98% was determined. It has been seen that in the indicated invariant point, the liquid phase is equilibrated with two solid phases: Ba(H2PO2)2. H2O and NaBr. The methods for separating NaBr and Ba(H2PO2)2 salts from natural salts and salt mixtures in industrial wastes can be applied and used in the processing and preparation of physicochemical principles.
