摘要：
Anions PO43-, CO32-, HPO42-, SO42-, and SCN- inducing establishment of the two-phase equilibrium in water-polyethylene glycol-inorganic salt systems are characterized by weak interaction with water (negative hydration, ΔG > 0) and positive but weak deviation from Raoult's law in water-salt γH2O > 1.0) binary subsystems.
