Liquid-liquid extraction intensification with magnetite nanofluid single drops under oscillating magnetic field
E-mail:
The influence of an oscillating magnetic field was investigated in mass transfer from magnetite nanofluid single drops in liquid-liquid extraction process. The chemical system of toluene-acetic acid-water was used, while hydrophobic magnetite nanoparticles were present in the organic dispersed phase. The magnetic field intensity was within the range of 0.36-1.45 T, accompanied with different nanofluid concentrations within 0.001-0.005 wt%. Compared with no magnetic field, an average enhancement of about 65% and a maximumof 121% (for the smallest used drops) were achieved. This essentialmatter can be attributed to the induced nanoparticles micro-convection inside the drops.
