FIELD: chemistry.
SUBSTANCE: invention can be used in extracting metals from water solutions. The method of preparation of sorbents includes the stages of alkaline sedimentation of yttrium or zirconium oxyhydrate, maturing of sediment, separation, dehumidification, granulating of sorbent, treating with the monochromatic beam of the ultraviolet light of the xenon lamp DCS-400 with wave 260 or 352 nm with use of prismatic monochromator, within 5 minutes.
EFFECT: invention increases sorption capacity.
