摘要
根据电解质溶液理论,在对NRTL方程进行简化的基础上,建立了计算IDANaClH2O三元体系溶解度的数学模型.采用本模型,对IDANaClH2O三元体系在0～60℃范围内的溶解度随温度变化关系进行了回归,并与实测结果进行了比较分析,结果令人满意.同时从理论上解释了氯化钠含量对IDA溶解度的影响.
The solubilities of iminodiacetic acids (IDA) were measured at different concertrations of NaCl solution at the temperature ranges from 0～60 ℃. An extended Electrolyte NRTL model of Chen was applied to the ternary system consists of IDA-NaCl-H_(2)O. The solubilities at different temperature were correlated and predicted.The results are coincided well with the experimental date.
