| Research Abstract |
The removal of toxic anions such as As(III), As(V), Se(IV), Cr(VI), B was conducted with the hydrotalcite-like compounds (HT) which were synthesized from the wastes or by-products in an aluminum regeneration process. The development of removal process was also tried for various toxic anions. The removal properties of toxic anions with the HTs derived from reagents or the wastes can be clarified in detail. It is possible to fix anions captured in the HT by a heat treatment. It is found that the concentrations of toxic anions blow effluent standards can be achieved by using the HTs.
