Investigation of the impact of synthesized hydrophobic magnetite nanoparticles on mass transfer and hydrodynamics of stagnant and stirred liquid–liquid extraction systems

•Finest magnetite nanoparticles with high hydrophobicity characteristic were synthesized.•In the single drop experiments, extraordinary enhancement of mass transfer was found.•In stirred column, mass transfer augmentation of nanofluid was negligible.•Mass transfer enhancement of nanofluids decreased...
