Magnetite Properties


Molecule Structure Image



Magnetite is a ferrimagnetic mineral, one of several iron oxides and a member of the spinel group. Magnetite powder efficiently removes arsenic(III) and arsenic(V) from water, the efficiency of which increases ~200 times when the magnetite particle size decreases from 300 to 12 nm. Arsenic-contaminated drinking water is a major problem around the world, which can be solved using magnetite as a sorbent.
