Moreover, water is the major component
in both phase [15], thus providing an environmental safe
extraction system, that eliminate the use of harmful organic solvents.
Thus, the extraction procedure that involve the use of aqueous
two-phase systems are considered compatible with the
principles of green chemistry [16], and other advantages of these
are ease to use, low cost, short time for phase separation and the
possibility to recycle the system components [17,18].
