Аннотация

Methods related to the ferritization treatment of waste water containing the heavy metal ions are presented, and their advantages with regard to the other physical-chemical technologies. A role of ζ-potential of micro particles Fe3O4 in the formation of spinel structures is discussed. Its values are shifted from 6-8 mV to electronegative zone, along with the pH shift from the acid to alkaline zone. The isoelectric point is reached at рН=6,5, which corresponds to the beginning of ferritization process. The mechanism of ferritization reactions is connected with the catalytic nature of the processes and probability of the intermediate active radicals formation.
