Kinetics Analysis of Decomposing Tributylphosphate with Non-Thermal Plasma

Non-thermal plasma technique can be used to degrade radioactive liquid waste involving Tributylphosphate (TBP) producing in nuclear fuel reprocessing. The dissociation reaction caused by the collision of electrons with neutral molecules can generate active radicals which play a central role in removing TBP. And the electron reacting with vapor to generate OH radicals is the key reaction in removing TBP. A model is derived from the Boltzmann equation and molecule collision theory to predicate the dissociation reaction rate coefficients. Upon comparing with available literature, the model is confirmed to be acceptably accurate in general. Reaction rate coefficients of vapor dissociation in non-thermal plasma are derived according to the Arrhenius formula.
