METHOD FOR ABSORBING WATER WITH A PH LESS THAN FOUR. |
abstract |
A method of absorbing water in the form of an aqueous agent having a pH of less than four. The method includes contacting said aqueous agent with a water swelling polymer comprising a salt of an alkali metal sulfonic acid containing a crosslinked polyelectrolyte in an amount sufficient to allow swelling of said 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 or battery bodies, for example. |
