Abstract

A highly selective and rapid electrochemical assay of the improvised explosive urea nitrate (UN) is reported. The method involves a short (∼10 s) acid-catalyzed reaction of UN with 4-nitrotoluene (NT) followed by a rapid (∼2 s) square-wave voltammetric (SWV) detection of the 2,4-dinitrotoluene (DNT) product. The new protocol offers great promise for a reliable field detection of UN, with significant advantages of speed, sensitivity, portability, simplicity, and cost.
