Hi, I am currently trying to model a simple water-salt solution (eg: NaCl-H2O or LiBr-H2O). I have found experimental data giving me the coefficients required for the ENRTL (electrolyte non random two liquid) model. However I am inserting these coefficients into the model as I have found it on research papers. These model descriptions are quite complex however as they are designed for multicomponent systems, and hence I have not been able to obtain a set of correct results yet. Are there any books which can simply walk me through the ENRTL model and outline all assumptions and terms within? Any help which you can give me would be hugely appreciated as I have been stuck on this for quite a while now and cannot make any progress. Thanks!!
