| 摘 要： | 通过湿渣法测定了水中NH4Cl和NaCl的溶解度数据,同时研究了三元水盐体系NaCl-NH4Cl-H2O在25℃时的固液相平衡关系。采用Pitzer模型计算了该三元水盐体系相平衡溶解度,比较了计算值和实验值,结果基本吻合。并从定量的角度描述了θNaNH4和ΨNaNH4Cl各以±10%变动时,对体系溶解度的影响。

| Abstract: | Using moist solid method,the phase equilibrium of ternary water-salt system NaCl-NH4ClH2O at 25℃ was investigated.The solubility data of NaCl and NH4 Cl in water were obtained.Pitzermodel method was utilized to calculate the solubility data of phase equilibrium for ternary water-salt system.The results show the coincide between the calculated value and experimental value.Furthermore,the solubility predicition results of NaCl-NH4Cl-H2O system at 25℃are calculated,and solubility variations of the system whenθNaNH4andΨNaNH4Clwere changed with±10%. |
