IONIC LIQUID BASED AQUEOUS TWO PHASE SYSTEMS

Aqueous two phase systems provide an alternative and efficient approach for the
extraction, recovery and purification of biomolecules through their partitioning
between two liquid aqueous phases. Throughout this project, the ability of
hydrophilic ionic liquid to form aqueous two phase systems with aqueous K3P04
solutions will be evaluated. Phase diagrams, tie-lines and tie-lines length will be
measured. The studied of ionic liquid have shown more effective in promoting
aqueous two phase systems compare to volatile organic solvents. The composition of
each ionic liquid and aqueous salt solution will be identified at bottom and top phase
at each point respectively. Densities and viscosities of both aqueous phases will also
be determined.
