Abstract:
The diagnosis of irradiance particles produced in the plasma degradation of diisopropyl fluorophosphates (DFP) was studied by spectral method. The characteristic peaks of [O],[O+],[O2+] were obtained by analyzing spectra intensity changes in condition of different discharge parameters. As a result, it is found that the intensity of [O] peaks disappear when DFP is involved in the reaction. Moreover, for [O+] peaks, the intensity drop of 398.69 nm was 70.1%, and other three peaks disappeared, and for [O2+] peaks, the intensity drops of 226.49 nm and 231.19 nm were 95.3% and 94.5%, and 216.92 nm peak disappeared, which means [O], [O+] and [O2+] play important roles in the degradation of DFP by plasma.
