| 摘要 |
Fluoride ion recovery from solutions with anion exchange resin. This process is rendered much more effective by using weak or, especially, medium anion exchangers containing active groups- N(R)2 and/or -N(R)3OH, whose capacity with respect to fluoride ions (concentration in solution 0.2-60g/l pref. 0.5-40g/l) exceeds 3-4 times their normal anion exchange capacity. |
