摘要
本文应用热力学基本原理和方法研究硫酸钾溶解平衡 ,结果表明 ,硫酸钾在纯水中的溶解度随温度变化符合前人总结的实验规律 ,而在 43℃的钛白废液中硫酸钾有反常溶解现象 ,这为确定硫酸钾结晶析出的最佳温度提供了热力学依据。通过热力学计算 ,论证了硫酸钾溶解平衡符合热力学基本原理。
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.
