A composition for capturing, removing, and in some cases recovering a pollutant or raw material wherein the composition includes a polymeric material, one or more metal or nonmetal materials in granular form, and preferably a small amount of a salt material.

Cartridges useful in regenerating or purifying dialysis solutions are described as well as methods to regenerate or purify spent dialysis solutions. Dialysis methods using the sorbent cartridges of the present invention are further described.

A sorbent cartridge comprising one or more detachable modules. The sorbent cartridge can have one or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein recharged. The sorbent cartridge can include a module containing an anion exchange resin, such as zirconium oxide, downstream of zirconium phosphate in the sorbent cartridge to recapture phosphate anions that leach out of the zirconium phosphate.

The invention relates to devices, systems, and methods for conditioning a zirconium oxide sorbent module for use in dialysis after recharging. The devices, systems, and methods can provide for conditioning and recharging of zirconium oxide in a single system, or in separate systems.

Parallel modules for in-line recharging of sorbent materials using alternate duty cycles for a sorbent cartridge. The sorbent cartridge can have two or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein can be recharged.

A detachable module for optionally recharging sorbent materials, including zirconium phosphate, with an optional bypass and conduits for a sorbent cartridge. The sorbent cartridge can have one or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein recharged.

A crystalline material contains oxygen, aluminum and phosphorus, and has powder X-ray diffraction peaks shown below. When the peak at 2=14.170.2 is used as the reference peak and the intensity of the reference peak is set to 100, for example, the relative intensity of the peak at 2=8.650.2 is 1 to 15. The relative intensity of the peak at 2=9.990.2 is 1 to 15. The relative intensity of the peak at 2=16.520.2 is 5 to 80. The relative intensity of the peak at 2=17.370.2 is 1 to 15. The relative intensity of the peak at 2=21.810.2 is 10 to 80.
