摘要/Abstract

摘要： 采用平衡分析法，测定了常压下铬铁矿液相氧化生产铬盐工艺分离过程涉及的NaOH-H₂O-Na₂CrO₄、NaOH-H₂O-NaAlO₂、NaOH-H₂O-Na₂SiO₃三元体系，NaOH-H₂O-Na₂CrO₄-Na₂SiO₃、NaOH-H₂O-Na₂CrO₄-NaAlO₂、NaOH-H₂O-Na₂SiO₃-NaAlO₂四元体系及NaOH-H₂O-Na₂CrO₄-Na₂SiO₃-NaAlO₂五元体系中Na₂CrO₄、NaAlO₂、Na₂SiO₃的溶解度，并使用Apelblat方程对实验数据进行了回归。实验的温度范围为353.15～403.15 K，除测量Na₂CrO₄在NaOH-H₂O-Na₂CrO₄三元体系中的溶解度时NaOH的浓度从100 g·L^-1改变到 800 g·L^-1，其他体系中都固定NaOH浓度为500 g·L^-1。研究结果表明铝酸钠、硅酸钠无论单独存在还是同时存在均会降低铬酸钠的溶解度，其中铝酸钠对铬酸钠的溶解度影响最大，而硅铝共存反而对铬酸钠溶解度影响最小。

Abstract: The solubility of Na₂CrO₄, NaAlO₂ and Na₂SiO₃ in the multicomponent systems related to the manufacture of chromium compounds by liquid-phase oxidation of chromite was measured by using the equilibrium analysis method at the atmospheric pressure and temperature ranging from 353.15 K to 403.15 K, which include ternary systems NaOH-H₂O-Na₂CrO₄, NaOH-H₂O-NaAlO₂ and NaOH-Na₂SiO₃-H₂O, quaternary systems NaOH-H₂O- Na₂CrO₄-Na₂SiO₃, NaOH-H₂O-Na₂CrO₄-NaAlO₂ and NaOH-NaAlO₂-Na₂SiO₃-H₂O, and quinary systems NaOH-H₂O-Na₂CrO₄-Na₂SiO₃-NaAlO₂. Except the Na₂CrO₄ solubility in ternary system NaOH-H₂O-Na₂CrO₄, in which NaOH concentration varied from 100 g·L^-1 to 800 g·L^-1, the NaOH concentration was constant at 500 g·L^-1. The experimental data were correlated by the Antonie equation, λ-h equation, and Apelblat equation, demonstrating that the Apelblat equation can well predict the solubility of the systems. The results show that the presence of NaAlO₂ and Na₂SiO₃ decreases Na₂CrO₄solubility, while the coexistence of NaAlO₂ and Na₂SiO₃ has less effect than the presence of single NaAlO₂ and Na₂SiO₃.
