Abstract: The disclosure relates to systems and methods for generating a brine solution using a salt bag for recharging zirconium phosphate in a reusable sorbent module. 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.

Abstract: Proposed is an inorganic ion-exchanger, which is selective to lithium and constituted a non-stoichiometric compound in the form of solid particles of a polymeric aqua-oxo-hydroxo complex represented by the following general formula: HaNbO(2.5+0.5·a).cZrO2.dH2O, wherein: “a” is a number ranging from 0.5 to 1.5, “c” is a number ranging from 0.01 to 1.0, and “d” is a number ranging from 0.1 to 2.0. The complex has a total ion exchange capacity of at least 3.5 meq/g and an ion-exchange capacity specifically to lithium of at least 2.5 meq/g. This ion-exchanger is intended for selective extraction of lithium from lithium-containing natural and industrial brines.

Abstract: A process for removing Co2+, Pb2+, Cd2+ and Cr3+ toxins from bodily fluids is disclosed. The process involves contacting the bodily fluid with an ion exchange composition to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchange composition. The ion exchange compositions are represented by the following empirical formula: AmZraTibSncMdSixOy. A composition comprising the above ion exchange compositions in combination with bodily fluids or dialysis solution is also disclosed. The ion exchange compositions may be supported by porous networks of biocompatible polymers such as carbohydrates or proteins.

Abstract: A method of sorbent dialysis is provided for enhanced removal of uremic toxins, such as toxic anions and/or organic solutes, from spent dialysate. More highly adsorbable zirconium polymeric complexes of these anions and/or organic solutes can be initially formed in spent dialysate by treatment with zirconium salt solution or other zirconium cation source, and then removed with adsorbent to provide purified or regenerated dialysate. Sorbent dialysis systems for detoxifying spent dialysate containing toxic anions and organic solutes are also provided.

Abstract: A process for removing Pb2+ ions from fluids, such as gastrointestinal fluids is described. The process involves contacting gastrointestinal fluid with a particulate metal titanate ion exchanger represented by the empirical formula: AmTixMyOz where A is an exchangeable cation selected from the group consisting of potassium ion, sodium ion, lithium ion, calcium ion, magnesium ion, hydronium ion, and mixtures thereof, and M is optionally at least one framework metal selected from niobium (5+), zirconium (4+), tin (4+), iron (3+), iron (2+), cobalt (2+), and manganese (2+). The particulate metal titanate ion exchangers of the present disclosure are synthesized in the presence of complexing agents, including at least one multihydroxyl-containing complexing agent (MHCA), which facilitate metal transport and incorporation while imparting beneficial properties such as large aggregate size, well-behaved particle size distribution, and macroporosity.

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: A process for removing Sr2+ toxins from bodily fluids is disclosed. The process involves contacting the bodily fluid with an ion exchanger to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchanger. The ion exchangers are represented by the following empirical formula: AmZraTibSncMdSixOy.
