    Abstract: A method and solution for eluting one of antimony(V) and a mixture of antimony(III) and antimony(V) from an ion exchange resin, comprises contacting the resin with an eluting solution comprising thiourea having a concentration of at least 0.002 M and hydrochloric acid having a concentration of at least 3 M. The method can be used for electrolytes in an industrial electrorefining process, by the further steps of contacting the electrolyte with an ion exchange resin to adsorb the antimony from the electrolyte and separating the resin from the electrolyte, before contacting the resin with the eluting solution comprising thiourea and hydrochloric acid. The method and solution address the difficulties of removing antimony(V), and allow for increased reuse of the resins.

    Abstract: An ion exchange membrane (52) for a fuel cell comprises a polymer having an acid functional group normally including protons, and having alkali metal ions partially ion-exchanged with the protons of the acid functional group of the membrane. The partial ion exchange of alkali metal ions into the membrane relates either to patterning of the exchanged ion make-up of the membrane, with some being ion exchanged and some not, or to the extent or concentration of the ion exchange in any particular location, or to both.

    Abstract: The invention relates to a process and a device for enriching water, in particular drinking water, with magnesium ions. In order to enable enrichment of water with magnesium ions in exchange for calcium ions and/or heavy metal ions during treatment of water, and in particular of drinking water, it is proposed according to the invention to pass the water through an ion exchanger which contains a weakly acidic ion exchange material, wherein at least a part of its ion exchange capacity is loaded with magnesium ions.

    Abstract: The automatic regenerable cold/hot water softener includes a water softening tank having ion exchange resin and a regenerating tank filled with regenerating substance of the ion exchange resin. The water softener controls the mode for receiving raw water and discharging soft water using one switching valve, a direct water mode for discharging raw water itself, a regeneration mode for regenerating ion exchange resin, and a intermittence mode for intermitting the inflow and outflow of the raw water and the soft water. The precise regeneration time is judged according to used amount of the soft water by a temperature sensor and a flow meter for sensing temperature and flux of supply raw water. The regeneration is automatically prosecuted by a control part having a microprocessor. The cold/hot water softener serves a user's convenience in that sudden change of temperature is prevented.
