Abstract: A method for preparing an adsorption unit for lithium recovery and use of the adsorption unit. The method includes preparation of an adsorption unit by performing extrusion forming on pulverized lithium adsorbent resin or a lithium adsorbent precursor and an adhesive, the adsorption unit has both high selectivity and adsorption amount of the lithium adsorbent resin and can achieve high-efficiency adsorption of lithium in water with an ultra-low lithium content, and when the adsorption unit is used for adsorbing lithium in the water with the ultra-low lithium content, the entire adsorption process is simple, the desorption efficiency is high and the cost is low.

Abstract: The present invention includes a novel salt-free water softening method that utilizes an exchange medium (such as a gel exchange polymer, a macroporous exchange polymer, or an inorganic cation exchanger) that is pre-loaded with a polyvalent cation that has low solubility in aqueous phase at nearly neutral pH. The method of the invention does not require use of a sodium salt or mineral acid in the regeneration of the exchange medium.

Abstract: A new family of rare-earth silicate compositions and the synthetic methods used to prepare them. The materials have open-framework structures and are characterized by their ion-exchange properties. They are represented by the following empirical formula: Ar+pMs+1−xM′t+xSinOm where A is an exchangeable cation such as sodium, M is at least one element selected from the group of rare-earth elements, and M′ is a framework metal having a valence of +2, +3, +4, or +5. The rare-earth silicate materials have utility in various cation-exchange applications such as dialysis and removal of toxic metals from the gastrointestinal tract.

Abstract: Systems and methods for generating a brine solution using a salt bag for recharging zirconium phosphate in a reusable sorbent module are provided. The salt bag can be a double layer bag. An inner water permeable bag can contain solid salts and can be surrounded by an outer water impermeable bag. Water can be added to dissolve the salts in the inner bag and the resulting solution can be collected as a brine solution for use in recharging the zirconium phosphate.
