Abstract

A new theoretical approach to 1:1 electrolytes at low temperature is developed, RPM and SAPM are studied with this approach, and their critical points of first order phase transition are calculated. The result is in very good agreement with that of recent MC simulations, in particular it shows that, for SAPM, both the critical temperature and critical density decrease with the increase of size asymmetry.
