METHOD OF PREPARING ZIRCONIUM DIOXIDE-BASED INORGANIC SORBENT

摘要

FIELD: sorbent production. SUBSTANCE: invention relates to preparation of granular hydrated zirconium dioxide used commonly as sorbent and catalyst. Sol of hydrated zirconium dioxide containing 2-35 mol % of aluminium is in-drop dispersed into ammonia solution, resultant grains are washed with water and dried at 100-900 C for 6 h. EFFECT: increased strength of sorbent.
