Zirconium phosphate recharging method and apparatus
First Claim
1. A solution for recharging zirconium phosphate, comprising a combination of at least one sodium salt and at least one acid, the solution having a predetermined pH value that results in a substantially consistent pH in a dialysate passing through the zirconium phosphate after the solution is used for recharging zirconium phosphate.

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.
