dc.descriptionAbstract: Research aimed at the development of a fiber-optic based sensor is described for in-situ detection of TNT in groundwater. Three approaches were evaluated in depth. All three involved use of a material to concentrate TNT in the field of view of an optical fiber. The materials tested were 1) a concentrated dextran solution isolated by a semi-permeable membrane; 2) a pre-swollen cross-linked polyvinyl alcohol polymer; and 3) an amine-loaded PVC membrane. Another approach based on the formation of a colored-TNT anion at high pH was also considered. The amine-loaded PVC membrane appears to have the most promise. Clear membranes were prepared which reacted with TNT to form a colored product. Measurement is made at 520 nm which is very convenient for fiber optic-based sensing. Various primary amines were assessed.-
