摘要
本文利用Ｐｉｔｚｅｒ电解质溶液理论．以盐的平衡常数作为平衡的判据，借助于计算机。对２５℃时，Ｎａ~＋，Ｋ~＋∥Ｃｌ~－，ＮＯ－Ｈ＿２Ｏ四元交互体系溶解度数据进行了计算，并举例展示了理论计算结果在工艺参数确定上的应用。
Based on Pitzers theory of the electrolyte solution,using equilibrium constants of salts as the conditions of dissociating equilibria and with the help of computers, thispaper has calculated the solubilities of quaternary reciprocal system Na￣+,K￣+∥Cl,NO H_2O at 25℃,and given an example to show the application of the results obtained in techno-logical parameter calculation.
