FIELD: chemistry.
SUBSTANCE: method comprises reacting a ferric salt with sodium hydroxide in an aqueous medium containing fibrillated cellulose fibres (FCF). The resultant ferric hydroxide particles are immobilised on the FCF to form a sorbent. The obtained sorbent contains ferric hydroxide in amount of 2500 pts.wt per 100 pts.wt fibres.
EFFECT: obtained sorbents are effective in treatment of waste water and process water containing reduced sulphur compounds and other contaminants.
