3.1. Type of extraction and dispersive solvents
The type of extraction and dispersive solvent may influence significantly
the extraction efficiency. The dispersive solvent is responsible
by increasing the interfacial surface between the extraction solvent
and aqueous phase. Therefore, dispersive solvent needs to be miscible
in the extraction solvent and aqueous phase. On the other hand, the
extraction solvent must be immiscible in aqueous phase, allowing
