摘要
研究硫酸钠在超临界水中的溶解度。在实验范围内 (4 0 0 5 0 0℃ ,2 2 .5 30MPa)测得溶解度均小于40× 10 -6g/g。随温度降低和压力升高 ,硫酸钠溶解度增大。关联了溶解度模型 ,表明同一温度下的硫酸钠溶解度对数与水密度对数呈线性关系。
The Solubility of sodium sulfate in supercritical water was studied.The results indicated that the solubility was less than 40×10 -6 g/g under the experimental conditions (400～500℃,22.5～30MPa).The solubility of sodium sulfate increased with decreasing pressure and increasing temperature.The experimental results also showed that at the same temperature,the plots the logarithm of solubility vs.the logarithm of the density of water yielded a straight line.
