NaCl+NaH2PO2+H2O Üçlü Sisteminin 333 K’de Çözünürlük ve Fizikokimyasal Özellik Değişimlerinin İncelenmesi

Öz

NaCl+NaH₂PO₂+H₂O üçlü sisteminin 333 K’de katı-sıvı denge verileri ve fizikokimyasal özellikleri izotermal yöntem kullanılarak araştırılmıştır. Katı faz bileşimleri Schreinemaker yöntemi ile belirlenmiştir. NaCl+NaH₂PO₂+H₂O üçlü sisteminin basit ötonik yapıya sahip olduğu tespit edilmiştir. Faz eğrisinde, bir ötonik nokta, iki invariant eğrisi ve iki kristallenme bölgesi görülmüştür. Kristallenme bölgelerinde NaCl ve NaH₂PO₂.H2O yapıları tespit edilmiştir. NaCl+NaH₂PO₂+H₂O üçlü sisteminde NaH₂PO₂’in NaCl üzerine salting-out (çözeltiden tuz uzaklaştırma) etkisi gözlenmiştir.

An Investigation of the Solubility and Changes in Physicochemical Properties of NaCl+NaH2PO2+H2O Ternary System at 333 K

Öz

Solid-liquid equilibria and physicochemical properties of NaCl+NaH₂PO₂+H₂O ternary system were investigated using isothermal method at 333 K. Solid phase compositions were obtained via Schreinemaker method. NaCl+NaH₂PO₂+H₂O ternary system is simple eutectic type. One eutectic point, two invariant curves and two crystallization areas were seen in phase diagram. NaCl and NaH₂PO₂.H₂O salts were determined in solid phase. It has been observed that NaH₂PO₂ has salting-out effect on NaCl in NaCl+NaH₂PO₂+H₂O ternary system.
