摘　　要：根据冷冻提硝的现状,对我国硫酸钠型盐矿卤水在0-～20℃范围内硫酸根浓度的变化进行了试验研究,获得了该条件范围内的硫酸根浓度变化规律并提出了硫酸根溶解度的经验式,为优质液体盐的制备提供了理论依据。According to the status quo of extraction of Glanber＇s salt by freezing process, the writers have made experimental study on the change of concentration of sulfate radical in sodium sulfate type brine at a temperature range between 0℃and -20℃.The changing rule of concentration of sulfate radical in this range is abtained and the empirical formula of sulfate radical solubility is put forward,which provides theoretical basis for making high quality liquid salt.
