CO sub(2) switchable dual responsive polymers as draw solutes for forward osmosis desalination

Low molecular weight dual responsive polymers, after purging with CO sub(2), become polyelectrolytes with high osmolality, which can be used as draw solutes for seawater desalination. These polymers precipitate above their Lower Critical Solution Temperature (LCST) after removal of CO sub(2)viapurgi...

Summary:Low molecular weight dual responsive polymers, after purging with CO sub(2), become polyelectrolytes with high osmolality, which can be used as draw solutes for seawater desalination. These polymers precipitate above their Lower Critical Solution Temperature (LCST) after removal of CO sub(2)viapurging with inert gas for ease of recovery and reuse.
