A method and a device for the detection of trinitrotoluene (TNT) in efflu water from the purification apparatus of ammunition plants is described. The tube detector utilizes a basic oxide section to convert the TNT to its Meisenheimer anions, followed by an alkyl quaternary ammonium chloride ion-exchange resin which collects the colored anions. The length of the resultant stain is proportional to the concentration of TNT in the water.

Field detection of 2,4,6-trinitrotoluene in water by ion-exchange resins

A holographic optical article of manufacture and a process for making it made from a polymeric material in the form of film which is transparent in the infrared region and which is photochemically modified to change its index of refraction.

Process of making a holographic optical article

A method for analyzing water for .alpha.-trinitrotoluene comprising the ss of allowing the water to flow over an ion exchange resin which contains a quaternary ammonium group and observing to determine whether or not a chemical reaction takes place.

Analytical method for TNT in water

An air-reactive chemiluminescent formulation is encapsulated and material ich will catalyze the reaction of the formulation with air is affixed to the outside of the capsule. When the capsule is crushed, the formulation, air and the catalyst all come into contact with one other and high intensity light is produced rapidly.

Chemiluminescent warning capsules

Tetraalkylammonium trifluoroacetates, lithium trifluoroacetate and sodium ifluoroacetate are disclosed as being useful as catalysts in chemiluminescent systems wherein a hydrogen peroxide component and an oxalate ester-fluorescer component are mixed and reacted to produce light.

Method of producing light using catalyst chemiluminescent system

A signal device combining a fluorescent or phosphorescent light tube and a ovel base to be thrown or dropped from a vehicle as a warning marker. The light tube may be of the chemically actuated type and the base preferably has four pivotally attached resilient legs serving to ensure that the device will assume an angular position of about 45.degree. when dropped.
