Abstract The bromine extraction processes by air blow-out method from seawater and brine have been widely used at home and abroad. In this paper,the gas-liquid equilibrium data for bromine-concentrated seawater at 30 �� and 40 �� at atmospheric were obtained with the bubble equilibrium equipment. All experimental equilibrium data were carried out by using Margules Equation for liquid phase and ideal e- quation for gas phase. The parameters of Margules model for the system were regressed by nonlinear least square method,and the calculated data from Margules model accorded well with the experimental data.
