METHOD OF PRODUCING SORBENTS BASED ON Zn(OH)AND ZnS ON CELLULOSE FIBRE SUPPORT

摘要

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)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.3 cl, 3 ex
