FIELD: power industry.
SUBSTANCE: method involves water filtration through loading of granulated ferrocyanide-containing sorbent; sorbent includes 0.2-2 wt % of hydrazine, 35-48 wt % of water and 20-35 wt % of nickel ferrocyanide; composition Me(I)4-2x[NixFe(CN)6], where Me(I) - Li+, Na+, K+, NH4 + or their mixture, x=1.2-1.8, the rest is zirconium hydroxide. Size of composite sorbent granules is 0.05-1.5 mm.
EFFECT: increasing cleaning coefficient and operational life of sorption loading.
