摘要
依据Pitzer电解质溶液理论对含有固溶体结晶区的K2SO4-（NH4）2SO4-H2O水盐体系溶解度进行了计算,计算值与实验确定值相吻合,并针对该体系相图固溶体结晶区不易实验确定的问题,提出了计算确定的方法.
On the basis of Pitzer electrolyte solution theory, solubility of K2SO4-(NH4)2SO4-H2O aqueous salt system which contains a solid solution region is calculated, the calculated value agrees with experiment results. In accordance with the problem that solid solution region is not easy determined in the phase diagram of the above system, a method to determine a solid solution region is put forward.
