摘要
Methods and systems for producing a moisture swing sorbent for carbon dioxide capture from air are disclosed. In some embodiments, the methods include the following: providing a heterogeneous ion-exchange material; soaking the material in deionized water; washing the material in hydroxide or carbonate solutions; rinsing the material in deionized water; collecting and titrating residuals of the soaking and the washing steps into a residual solution; measuring an amount of chloride in the residual solution; repeating all of the steps if the amount of chloride measured in the residual solution is greater than zero; and drying the material with either dry nitrogen gas or air free of carbon dioxide and water.
