The results of experimental studies of electrical and radiative properties of xenon flash lamps with a double quartz-sapphire envelope are presented. Comparative studies of xenon lamps with quartz and quartz-sapphire envelopes were carried out. The possibility of a significant increase in brightness temperature of the xenon plasma and radiation efficiency in germicidal range (200-300 nm) is shown. The achieved values of the brightness temperature of 10 kK and the radiation efficiency of 8.2 % in the germicidal range demonstrate the prospects of using the presented source of pulsed broadband radiation for disinfection of various objects.

The techniques of total spectral energy and electrical measurements of high-current pulsed arc discharge are presented and substantiated. On the example of a flash lamp, three working circuits were reviewed and the following values were obtained: time dependences for circuit electrical parameters, values of the energy deposition into plasma, and radiative efficiencies for different spectral ranges.

Pulse Рhotochemical Decomposition of Phenol in Wastewater

et al. 2020

Photochemical decomposition of phenol with a concentration of 5 to 24 mg/L using hydrogen peroxide and ultraviolet irradiation (UV/H2O2) was studied. Xenon flash lamp was chosen as a radiation source. It emits high-intensity continuous-spectrum radiation in a wide wavelength range from 200 to 1000 nm. The effect of the initial concentration of hydrogen peroxide and the source average radiation power on the phenol destruction rate were studied. An extremum in the dependence of the phenol decomposition rate constant on the initial concentration of hydrogen peroxide was found. Kinetic model of the process based on the obtained data was developed. It was tested by predicting phenol destruction rate with the different process parameters and gave good accuracy.
