フェライト法による重金属含有廃液の処理とスラッジの再資源化 Treatment of Waste Water Containing Heavy Metal Ions by Ferrite Process and Recycled Ferrite Sludge
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.
