摘要
采用等温蒸发法研究了四元体系Na+,K+//Cl-,NO3--H2O在298 K时NaCl-KCl单变量曲线的介稳现象及湿度对该线介稳程度的影响。研究表明:该体系的NaCl-KCl单变量曲线存在一定程度的介稳现象,在湿度低于50%RH范围内,较高湿度范围内测定的NaCl-KCl单变量曲线介稳程度更小。
Metastable equilibrium of NaCl-KCl univariant curve and the influence of humidity on it in the quaternary system Na+,K+//Cl-,NO3——H2O were studied at 298 K by isothermal evaporation method.According to the experimental data,metastable equilibrium occurred at the NaCl-KCl univariant curve,and,the lower humidity was,the more obvious metastable equilibrium of NaCl-KCl univariant curve showed when humidity was below 50% RH.
