We describe here a novel method using photoactivated fluorescence for the detection of trichloroethylene (TCE). The approach involves photoactivation by uv irradiation of TCE in the presence of a photoactivator, diphenylamine, subsequent excitation of the photoproduct complex, and detection of the luminescent photoproduct. The photoproduct exhibits new absorption fluorescent bands. Conventional fixed-wavelength excitation and synchronous luminescence (SL) are used for detection. [References: 14]
