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.
