| titleOfInvention | METHOD FOR REGENERATING ION EXCHANGERS |
| abstract | The ion exchange (I), exchanged with ions (II) which can be removed from aq. soln. electrolytically or galvanically by deposition or decompsn., is treated with the stoichiometric amt. of acid or base, in aq. soln., for the replacement of all exchangeable sites of (I) and, at the same time, the aq. soln. is electrolysed to deposit or decompose (II). If ions (III) which cannot be removed in this way or can only be removed with difficulty are present, the soln. is treated with a highly conc. (II) soln. and/or with ions (IV) of higher exchange potential, which can be removed electrolytically or galvanically, before electrolysis. Esp. used for the regeneration of (I) used for desalination of sea water; and also (I) used for demineralisation of boiler feed water, radioactive waste liquor processing and Cu recovery from the pptn. bath in rayon mfr. The min. amt. of soln. is needed for regeneration and a conc. soln. is obtd. which can be utilised or processed economically. In an example, a cation exchanger, satd. with Na+ (from NaCl soln.), was treated with conc. FeCl3 soln. The filtrate was electrolysed, whilst the exchanger was treated with H2SO4 and electrolysed to regenerate the H+ form. |
