Abstract: A system and method for the reduction of NOx and CO contaminants using an ion-exchange resin media having lower-valency ions of the transitional metal elements, such as ferrous ions, cuprous ions and/or manganese ions, such that gases containing NOx and/or CO contaminants may be passed over the media so that the contaminants are absorbed by the lower-valency ions of the transitional metal elements, the media configured so that it can be regenerated to remove the NOx and/or CO contaminants. Regeneration includes exposing the media to a heated stream of hydrogen gas or exposing the media to hydrogen ions in an electrochemical cell.

Abstract: Methods and related apparatuses for sorbent recharging are provided. The methods and related apparatuses for recharging can recharge a specific rechargeable layer or module of a sorbent material such as zirconium phosphate in a sorbent cartridge. The methods and apparatuses include a fluid source containing at least one recharging fluid, wherein the fluid source is fluidly connectable to at least one rechargeable sorbent module for use in sorbent dialysis in a fluid flow path. The methods and apparatuses include passing a single solution through the zirconium phosphate for ion exchanges, resulting in zirconium phosphate to maintain a substantially consistent pH in a dialysate used during dialysis.

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. 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.
