The removal of heavy metal ions from waste water containing heavy metal ions by the ferrite process were examined.<BR>For the waste water containing heavy metal ions, it has been found that the structure of the sludge was ferrite and that the heavy metal ions existed in a ferrite lattice as a stable solid solution, from the analysis of the sludge by X-ray diffraction patterns of the ferrite.<BR>The lattice constant measurement revealed that it was possible to remove heavy metal ions from model waste water up to a Co, Cu and Ni ions concentration of 2000 mg/<I>l</I>. And it was possible to remove Cr ions from model waste water up to a Cr ions concentration of 500 mg/<I>l</I>.<BR>The saturation magnetization of the Co-, Cu-, Ni-ferrite sludge was higher than the value of 60 emu/g required for application to magnetic materials. But the saturation magnetization of the Cr-ferrite sludge for magnetic materials.
