FIELD: chemistry.
SUBSTANCE: method includes treating a zinc salt solution containing fibrillated cellulose fibres with sodium hydroxide and/or sulphide. The formed particles of insoluble zinc compounds are immobilised on the fibres to form a sorbent. The obtained sorbent contains Zn(OH)2 and/or ZnS in amount of 50-800 pts.wt per 100 pts.wt fibre.
EFFECT: obtaining a product with high content of a sorption active phase.
