The effect of polymer molar mass for the aqueous two-phase systems Containing Polyethylen glycol and Di-sodium hydrogen citrate

Aqueous two-phase systems (ATPS) formed by mixtures of two polymers, or one polymer and one inorganic salt, are important for separation and purification of biological materials such as enzymes and proteins۱, ۲. In the present work, we report LLE data for aqueous mixtures of PEG۴۰۰۰ or PEG۶۰۰ +Na۲C۶H۶O۷ + H۲O at T= ۲۹۸.۱۵ K.
