Abstract
The present invention discloses a method for increasing absorbent capacity of a superabsorbent material (SAM) by treating the SAM with a selected salt or a combination of such salts. The selected salt(s) may interact with the polymer chain of the SAM through one or more absorbent capacity enhancement mechanisms. The absorbent capacity enhancement mechanism(s) between selected salt(s) and the SAM may lead to greater absorbent capacity of the SAM.
