Liquid–liquid extraction intensification with magnetite nanofluid single drops under oscillating magnetic field

The influence of silica nanoparticles on hydrodynamics and mass transfer in spray liquid–liquid extraction column

“…In each section, performed studies, type of nanofluids, size and concentration range of nanoparticles, mass transfer measurement method, maximum observed enhancement and suggested mass transport mechanisms were pointed out [13]. In the field of mass transfer in nanofluids, there are a few researches dealt with mass diffusion in nanofluids [1,9,[14][15][16][17][18][19][20] and more researches investigated the influence of nanoparticles on convective mass transfer [10,[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Nevertheless, most researches on convective mass transfer in nanofluids are related to the gas absorption processes [21][22][23][24][25][26][27][28][29][30] and there have been limited attempts to use nanofluids in other popular separation processes such as liquid-liquid extraction [10,[34][35][36]…”

“…Recently, Saien et al [40] investigated the influence of an oscillating magnetic field on mass transfer in a magnetite nanofluid single drop liquid-liquid extraction column. They used chemical system toluene-acetic acid-water, while hydrophobic magnetite nanoparticles were present in the organic dispersed phase.…”

“…Compared with no magnetic field, an average enhancement of about 65% and a maximum of 121% (for the smallest drops) were achieved in their experiments. Saien et al [40] believed that the mass transfer enhancement can be attributed to the induced nanoparticles micro-convection inside the drops.…”

Experimental investigation of the effects of the hydrophilic silica nanoparticles on mass transfer and hydrodynamics of single drop extraction

“…Among these researches, few are devoted to applying nanoparticles to liquid-liquid extraction processes [12][13][14][15][16][17][18][19][20].…”
