Abstract :
The decomposition of dioxin analogues by infrared (IR) laser irradiation includes thermal destruction and multiple-photon dissociation. it is important for the decomposition to choose the laser wavelength which is highly absorbed. The thermal decomposition takes place by the irradiation of the low IR laser power. Considering the model of thermal decomposition, it is proposed that the adjacent water molecules assist the decomposition of dioxin analogues in addition to the thermal decomposition by the direct laser absorption.
