FIELD: chemistry.
SUBSTANCE: sorbents are obtained by interaction of ferrous sulphate and calcium hydroxide in a water medium, which contains fibrillated cellulose fibres. Particles of iron hydroxide and calcium sulphate formed as a result of the interaction are immobilised on the fibres with formation of a sorbent.
EFFECT: increased content of an active phase in the sorbent.
