摘要
用Pitzer理论研究了混合电解质溶液的偏摩尔体积,建立了偏摩尔体积的预测方法,并利用所得电解质溶液的表观摩尔体积的Pitzer参数预测了HNO_3-UO_2(NO_3)_2-H_2O、KCl-Na_2SO_4-H_2O、NaCl-Na_2SO_4-H_2O、NaCl-CaCl_2-H_2O、KCl-CaCl_2-H_2O、KCl-MgCl_2-H_2O和KCl-NaBr-H_2O共7个系统4种类型的混合溶液的偏摩尔体积。
The partial molar volumes of mixed electrolyte aqueous solutions are calculated by using Pitzer theory, and the predicting equations were established. The partial molar volumes for HNOs-UO2(NO3)2-H2O, KCl-Na2SO4-H2O, NaCl-Na2SO4-H2O, NaCl-CaCl2-H2O, KCl-CaCl2-H2O, KC1-MgCl2-H2O, KCl-NaBr-H2O systems are estimated by using new Pitzer single and mixed parameters of apparent molar volumes, and compared with the partial molar volumes calculated from experimental densities. This paper establishes a new method for predicting the partial molar volumes of mixed electrolyte aqueous solutions.
