Anion Exchange Resins for the Detection of 2,4,6-Trinitrotoluene in Water

The reactions of 2,4,6-trinitrotoluene (TNT) with strongly basic anion exchange resins were examined with the ultimate goal being the development of a field detector for TNT in water.

Description
Summary:The reactions of 2,4,6-trinitrotoluene (TNT) with strongly basic anion exchange resins were examined with the ultimate goal being the development of a field detector for TNT in water. Initial work involved a study of the kinetics of the reaction of TNT with various anionic forms of anion exchange resins. The relative reaction rates observed were SO4(-2)C1(-)OH(-)CN(-). Bisectional indicator tubes were developed in which the TNT is first converted to its colored Meisenheimer anion and then trapped on an anion exchange resin. An estimate of the TNT concentration can be made by comparing stain lengths. Two indicator tubes have been developed. One for the 0.1-10.0 ppm range and another for the 30-100 ppb range. In an attempt to improve the indicator tubes, various techniques were examined for the manufacture of pellicular anion exchange resins.
