Synthesis of Aqueous Ferrofluid

Full procedure can be found at: https://education.mrsec.wisc.edu/synt...

A ferrofluid is a liquid made of nanoscale ferromagnetic particles dispersed evenly throughout a carrier fluid. Ferrofluids become very strongly magnetized in the presence of a magnetic field. Here, Fe3O4 magnetite nanoparticles are produced by mixing Fe(II) and Fe(III) salts together in a basic solution.
