A lattice model is presented to compute salt-induced liquid-liquid phase separation in aqueous polymer solutions. The Gibbs energy of mixing contains an electrostatic contribution given by Pitzer's extension of the Debye-Hu ¨ckel function, and the extended Flory-Huggins theory that uses empirical fu
