FIELD: chemistry.
SUBSTANCE: purification of water and water solutions from anions and cations is carried out by electrolysis by alternating asymmetric current with application of insoluble electrodes, electrolysis process is performed with air barbotage with bubble diameter larger than interelectrode distance with further introduction into solution of complexing agent -bivalent iron salt (FeSO4) with ratio 5:1 with respect to initial concentration of purified ion and further precipitation of solution for 8 days.
EFFECT: increased degree of purification and reduction of specific energy consumption.
