Removal of Beryllium Ion from Wastewater by Ferrite Process

Abstract

The removal of beryllium ions from complex component waste water containing beryllium and other heavy metal ions by the ferrite process were examined.
For the complex component waste water containing beryllium and heavy metal ions, it has been found that the structure of the sludge was ferrite and that the beryllium 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.
The lattice constant measurement revealed that it was possible to remove beryllium ions from model waste water up to a beryllium ion concentration of 100 mg/l.
The saturation magnetization of the sludge was higher than the value of 60 emu/g required for application to magnetic materials.
