Title: Regeneration of ion exchange resin
Inventor: KOIDE FUJIO
IPC: C02F1/42
Filed: 1983-05-04
Abstract: PURPOSE:To efficiently remove B in a high removal ratio by passing brine without diluting the same, by regenerating a B-selective resin brought into contact with brine containing B along with a large amount of Mg under a specific condition. CONSTITUTION:When brine containing B along with a large amount of Mg is allowed to pass through a B-selective resin layer, B is ion exhanged with the B-selective resin to obtain brine of which B-content is extremely low. When a B-leak is detected in the treated brine, brine supply is stopped and the regeneration of the B-selective resin is performed. In regeneration, a mineral acid solution such as hydrochloric acid or sulfuric acid is at first passed through the B- selective resin to dissociate B. In the next step, water is passed therethrough to wash the mineral acid solution remaining in the resin. Subsequently, an alkali solution corresponding to 20-60% equivalent on the basis of the acid equivalent of the aforementioned mineral acid solution is passed through said resin to partially convert the same from a salt-type to a free type (OH-type). By this method, the precipitation of Mg(OH)2 in brine during supply is prevented and B can be removed with good efficiency.
