Abstract
Methods and related apparatuses for sorbent recharging are provided. The methods and related apparatuses for recharging can recharge a specific rechargeable layer of a sorbent material such as zirconium phosphate in a sorbent cartridge. The methods and apparatuses include passing solutions containing combinations of acids, bases and salts through a module containing a rechargeable sorbent material such as zirconium phosphate in order to replace ions bound to the zirconium phosphate with hydrogen and sodium ions. The method allows for a customizable zirconium phosphate, with control over the ratios of sodium to hydrogen on the recharged zirconium phosphate.
