Boron extraction from aqueous medium using novel hydrophobic deep eutectic solvents

In this work, four novel hydrophobic deep eutectic solvents (DES) were prepared from a combination of menthol (Men) or thymol (Thy) as hydrogen bond acceptors (HBA) with 1-decanol (Dec) or 2-methyl-2,4-pentanediol (MPD) as hydrogen bond donors (HBD), for the extraction of boron from aqueous solutions. The DESs were characterized in terms of their physical (density, viscosity and water content), and thermal (melting point and decomposition...
