Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H.sup.+ZP within a casing for a treatment; and after the treatment, refurbishing the H.sup.+ZP while maintained within the casing via (i) regenerating the non-disinfected H.sup.+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H.sup.+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H.sup.+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H.sup.+ZP while maintained within the casing. Multiple batch sorbent refubishing implementations are also disclosed.

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.

The invention relates to systems and methods for disinfecting, recharging, and conditioning zirconium phosphate in a reusable sorbent module. The systems and methods provide for reuse of a zirconium phosphate sorbent module after dialysis.

In an improved superabsorbent complexed with aluminum ions, the aluminum ions are applied in the form of an aqueous solution comprising aluminum ions, which has the feature that it comprises aluminum ions in a proportion within the range of 0.5%-15% by weight (converted if appropriate to Al.sup.3+), based on the total mass of the solution, and further comprises anions of lactic acid (lactate ions) and phosphoric acid (phosphate ions), where the molar proportion of the lactate ions is within the range of 0.01-2.99 times the molar amount of Al.sup.3+ and the molar proportion of the phosphate ions is within the range of 0.01-2.99 times the molar amount of Al.sup.3+.

Methods and devices for providing dialysis treatment are provided. The device comprises a cartridge for providing regenerative dialysis, the cartridge comprising: a body having an inlet and an outlet and defining an interior, the interior including at least a layer comprising urease, a layer comprising zirconium oxide, a layer comprising zirconium phosphate, and a layer comprising carbon, wherein at least two of the layers are blended together to provide a gradient of the two materials.

The present invention provides a substance which is useful as a carrier for protein purification. Since an aluminum phosphate compound that is obtained by a method for producing an aluminum phosphate compound, which comprises a step for obtaining a mixture that contains an aluminum phosphate compound by mixing an aqueous solution A containing a phosphate ion with an aqueous solution B containing an aluminum ion and a sulfate ion, and at least one of a potassium ion or a magnesium ion, exhibits excellent protein adsorption properties, this aluminum phosphate compound is useful as a carrier for protein purification.
