    Abstract: Hypochlorite salts and substantially dehydrated acid-form cation exchange resin beads are combined at specified ratios within a porous enclosure such as a pouch or sachet. Hypochlorous acid solutions are produced on demand by introducing the mixture-containing pouch into a chemical excess of water. Spontaneous exchange reactions occur at room temperature within a few minutes to produce aqueous hypochlorous acid, while the cations from the hypochlorite salt are simultaneously sequestered by the resin beads. The resin beads remain contained within the original porous enclosure to allow mechanical isolation or separation from the resulting solution.

    Abstract: Disclosed is a new continuous lithium-sodium separation method. A lithium-sodium separation mother solution, a first leacheate, a desorption solution, a second leacheate and a lithium-sodium separation adsorption tail solution respectively pass through a lithium-sodium separation mother solution feeding pipe (2), a first leacheate feeding pipe (3), a desorption solution feeding pipe (4), a second leacheate feeding pipe (5) and an adsorption tail solution top desorption solution feeding pipe (6) that are located above and below a rotary disc of a multi-way change-over valve system (1), respectively enter corresponding resin columns (7) by means of pore channels and channels in the multi-way change-over valve system (1), and then are discharged from an adsorption tail solution discharging pipe (8), a first leacheate discharging pipe (9), a qualified liquid discharging pipe (10), a second leacheate discharging pipe (11) and an adsorption tail solution top desorption solution discharging pipe (12), so as to complete the whole technological process, wherein the resin columns (7) are connected in series or in parallel by means of the channels located in the multi-way change-over valve system (1). The method is simple and easy to operate, the resin utilization rate is improved by 20% or more, the efficiency is improved by 40% or more, and the production cost can be reduced by 30-50%. The production reliability is improved, and all-year continuous operation can be realized.

    Abstract: Disclosed herein is a process for carrying out an ion exchange process which involves providing two interacting sets of banks of continuously stirred tank reactors (CSTR's) each containing a bed of ion exchange resin and causing the resin to move in one direction through each bank of reactors and the feed solution and/or or eluant in the opposite direction. In carrying out the process, a feed solution is introduced in a first reactor causing dissolved ions to be captured on the resin, eluant is introduced into a reactor upstream of the first reactor in the direction of resin movement causing ions captured on the resin to be removed into the eluant and eluant rich in ions removed from the resin will be taken from a reactor upstream of the reactor in which the eluant was introduced, for further processing. Thus, in this form of the invention there is, in effect, a loading bank of reactors in which ions from the feed solution are captured followed by a regenerating bank of reactors in which the eluant removes the ions captured on the resin and regenerates the resin.
