A Study of the Isothermal Solubility of Ternary Systems CuSO4(ZnSO4)-CO(NH2)2-H2O at 30 ℃

Abstract

Abstract: CuSO₄-CO(NH₂)₂-H₂Oand ZnSO₄-CO(NH₂)₂-H₂O ternary systems have been in-vestigated by isothermal method at 30 ℃. Their solubility diagrams and refractive index-composition diagrams have been constructed. New ternary compounds formed in each system respectively, CuSO₄·3CO(NH₂)₂·H₂Oincongruently dissolved in the former system and ZnSO₄·CO(NH₂)₂·2H₂O congruently dissolved in the latter and new compounds were confirmed by IR, TG and X-ray diffraction methods.

Key words: Phase diagram, Ternary system, Phase equilibrium, Copper sulfate, Zinc salfate
