<p>A process for absorbing water containing relatively large amount of acid comprises contacting an aqueous medium with a rapidly water-swellable polymer comprising an alkali metal sulfonic acid salt containing polyelectrolyte. For example, a crosslinked polymer containing polymerized acrylamide and sodium 2-acrylamide-2-methylpropane sulfonate can be used to remove acidic water from fuels, battery casings, etc.</p> |
