Ionic liquids are an ideal alternative for organic solvents in chemical warfare agent decontamination due to their chemical and thermal stability and nonvolatile properties. In this project, DMPITf2N is used as the ionic liquid solvent for the decontamination of DFP by ethanolamine. The stability of DMPITf2N during decontamination reactions is investigated using capillary electrophoresis. Fluorine, phosphorus, and proton NMR spectroscopic analyses are used to monitor the degradation of DFP. Calibration curves are established using DFP with DMPITf2N, a fluorine standard, and a phosphorus standard in order to determine rates of reactions and efficacy of decontaminants.
