Process for the separation and recovery of polyethylene glycol (PEG) from spent aqueous two-phase systems |
| abstract |
A process for the separation and recovery of polyethylene glycol from a spent, aqueous two-phase system, comprising (a) separating the polyethylene glycol (PEG) rich upper phase from a spent aqueous two-phase system (ATPS); (b) exposing the separated PEG-rich phase to a microwave field; (c) irradiating the PEG-rich phase with the microwave field for a period in the range of 1.5-3 minutes or until the dispersion forms two phases with elimination of water to form the lower phase and a PEG-rich upper phase; (d) separating the PEG-rich upper phase and drying to obtain dry and powdered PEG having a recovery of 94-95%. |
