【Abstract】 This article used the basic principle and method of thermodynamic to study elementary regulation of potassium sulfate dissolution equilibrium.The result showed that the solubility of potassium sulfate in water was varied along with the temperature change which was compatible with the experiment done by previous work.The dissolution regulavity of potassium sulfate in 43℃ titan white liquid waste showed abnormal dissolution phenomenon.It provided thermodynamic evidence for the determination of optimum temperature of potassium sulfate crystal precipitation.Thermodynamic calculation indicated that the basic principle of theromodynamics was compatible with the dissolution equilibrium of potassium sulfate.更多还原
