摘　　要：以N2为惰性载气,研究了总气压为100.8～102.3kPa、温度为3～33℃、SO2分压为55～124Pa时SO2在不同盐度海水中的溶解度。研究结果表明,降低温度、增大SO2浓度及海水盐度有利于增加SO2在海水中的溶解度。以海水盐度、海水湿度及SO2分压为参数,拟合了预测SO2在海水中溶解度的二次方程,其相关系数R2为0.987。Taking N2 as inert carier gas, the solubility of sulpher dioxide with total pressure of （100.8- 102.3） kPa and temperature of 3-33 ℃in seawater with different salinity has been studied. Results of study shows that the decrease of temperature,and increase concentration of SO2 and the the salinity of seawater all are helpful to enhance the solubility of SO2 in seawater. A quadratic equation for predicting the solubility of SO2 in seawater has been formulated,it correlation coefficient R2 being 0. 987.
