ABSTRACT:
The invention herein provides for the detection of certain organic halogen-containing agents or toxicants such as sarin, chloropicrin, mustard gas, mustard chlorohydrin, phosgene, chlorine, soman, lewisite, diphosgene and others by, in one embodiment, first reacting the agents with superoxide free radical anion (.O{overscore (2)}) to produce light pulses which can be detected by a standard photon counter. The superoxide may be available from a dimethyl sulfoxide superoxide (.O{overscore (2)}) liquid solution, from lecithin coated beads charged with superoxide (.O{overscore (2)}) in a reaction vessel or from a quarternary ammonium ion exchange resin charged with superoxide anion (.O{overscore (2)}) in a reaction vessel.
