METHOD OF PRODUCING SORBENTS BASED ON MIXED GELS OF ZIRCONIUM OXYHYDRATE AND SILICIC ACID |
| 摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to sol-gel technology of producing sorbents based on gels of heavy metal oxyhydrates. The method involves combined deposition of zirconium oxyhydrate and silicic acid from solutions of sodium methacrylate and a zirconium salt in equimolar ratios. Deposition is carried out at pH 8-11 for one hour. The gel is then matured, the precipitate is washed, separated, dried and granulated. ^ EFFECT: high sorption capacity and selective properties of the sorbent. ^ 2 dwg, 1 tbl, 2 ex |
