Abstract

The invention provides reactive sorbents and methods of making and using the same in order to decontaminate surfaces contaminated with toxic agents, such as chemical warfare agents and/or industrial toxins. The reactive sorbents are of two general types, one of which comprises dehydroxylated aluminum oxide and the other comprises porous carbon impregnated with a reactive solution, so that both sorbents take up and then detoxify toxic agents.
