UV intensity measurement for a novel 222 nm excimer lamp using chemical actinometer

Photohydrate of uridine in neutral aqueous solution is used for the determination of the ultraviolet (UV) intensity of a novel excimer lamp, employing a dielectric barrier discharge in krypton chloride to provide intense narrow band radiation at λ=222 nm (KrCl*). The intensity measurement is based o...

Description
Summary:Photohydrate of uridine in neutral aqueous solution is used for the determination of the ultraviolet (UV) intensity of a novel excimer lamp, employing a dielectric barrier discharge in krypton chloride to provide intense narrow band radiation at λ=222 nm (KrCl*). The intensity measurement is based on UV spectral absorption data. A photokinetic model is presented for the reaction which is generally applicable for any photochemical system. The electrical power dependence of the UV intensity generated as well as the efficiency of the lamps was investigated.
