FIELD: metallurgy.
SUBSTANCE: invention can be applied in ferrous and non-ferrous metallurgy, as well as in industrial and domestic wastewater treatment. Method of chrome (III, VI) ion removal from wastewater involves contact of treated water with the mix of anionite with strong acid cationite, mixing and phase separation. Anionite of AMP or AM-2B grade is used as anionite. Strong acid cationite KU-2 obtained by sulphation of styrene copolymer and 8-20 % divinyl benzene is used as cationite.
EFFECT: fast and deep extraction of chrome (III, VI) from water medium.
