Paper Abstract

Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is employed to measure the spectral properties of a chemical agent simulant, ethyl methylphosphonate (EMPA) mixed with soil. DRIFTS is a quantitative technique that provides information about the intensity of vibrational absorption bands from the analyte in terms of the Kubelka-Munk model. The spectral properties of the neat oil, the soil matrix, and mixtures of the two over a range of relative proportions will be presented and discussed vis-a-vis the surface contamination detection problem.
