抄録

The ferrite process, one of the disposal methods for waste water containing heavy metal ions, has been applied for model waste waters containing beryllium ions. The stability of the solid solution incorporated beryllium ions in the ferrite lattice and the applicability of resultant ferrite sludge as recycled resources were examined by X-ray analysis and magnetometry. From the analysis of sludge the X-ray diffraction patterns for the ferrite, it has been found the structure of the sludge was beryllium ferrite and that the beryllium ions existed in ferrite lattice as a stable solid solution. The lattice constants measurement revealed that it was possible to remove beryllium ions from the model waste water up to a beryllium ion concentration of 40 mg/l and that the amount of beryllium ions soluble in the ferrite lattice was about 2 mg per 1g of ferrous sulfate. The saturation magnetization of the sludge was higher than the value of 60 emu/g required on application to magnetic materials.
