摘要
实验研究采用改进的鼓泡流动平衡釜测定了常压及20℃3,0℃和40℃下,含溴0.01 g/L～0.2 g/L的(浓)海水的气液平衡数据。通过对相平衡数据进行拟合得到了其亨利常数,并对实验数据应用Margules活度系数方程进行了关联处理,取得了较好结果,最后,研究了亨利常数同温度的关系,并利用Vant’Hoff公式进行了关联,为实际生产中的空气吹出法制溴的应用提供了研究基础。
In the experiment,the gas-liquid equilibrium data for bromine-seawater and bromine-concentrated seawater system at 20℃,30℃ and 40℃ in the atmosphere were obtained with the bubble-equilibrium still.The Henry＇s constants of the three systems at the different temperatures were obtained,and all the experimental equilibrium data were carried out by using Margules Equation for liquid phase and ideal equation for gas phase with good results.Moreover,the relationship between Henry＇s constant and temperatures was fit with Van＇t Hoff Equation.
