FIELD: chemistry.
SUBSTANCE: method involves sorption with an adsorbent, which uses an environmentally friendly, technological composite sorbent containing 80 wt % of the 95% glauconite concentrate of the Bondarskoye deposit of the Tambov region and 20 wt % SiO2. The sorbent is preliminarily subjected to successive alkaline and acid treatments and transferred to the Na-form in saline NaCl solution. The linear flow rate of technological and industrial wastewater is up to 0.5 m/h, while the sorbent layer height is from 0.01 m.
EFFECT: reducing the concentration of nickel ions in purified water.
