Hydrogen fluoride adsorbent and selective removal of hydrogen fluoride using the same |
| abstract |
The present invention provides a hydrogen fluoride adsorbent which comprises a porous polymer functionalized with an amine group and adsorbs hydrogen fluoride in an aqueous solution containing a hydrofluoric acid salt and hydrogen fluoride. The hydrogen fluoride adsorbent according to the present invention can selectively remove only hydrogen fluoride in an aqueous solution containing a hydrofluoric acid salt and hydrogen fluoride including a porous polymer whose surface is functionalized with an amine group. The method of removing hydrogen fluoride using the method is capable of selectively removing hydrogen fluoride contained in an aqueous solution containing a fluoric acid salt. Thus, the alkali metal fluoride finally obtained in the step of producing an alkali metal fluoride is high in purity, Since the large hydrogen fluoride is selectively removed from the aqueous solution in advance, the device can be protected during the recrystallization and drying process. |
