The Testing Equipment for Electron-Beam Exposure to Solutions of Organic Compounds

Abstract

Electron beam irradiation is of great interest to researchers as it opens up new opportunities for meaningful interdisciplinary collaboration between scientists from fields such as chemistry, physics, ecology, engineering, biology, nanotechnology, and materials science. The interaction of electrons with matter ensures the formation of highly efficient reactive particles. A setup for studying the interaction of an electron beam with a liquid is presented. The efficiency of transformation of dissolved organic compounds under the action of electron beam irradiation was evaluated using pulsed cathodoluminescence. The novelty of the study lies in the fact that the irradiation of solutions and the excitation of luminescence, which is used for diagnostics, are carried out simultaneously by the same electron beam. This setup is a tool for studying the physicochemical utilization of toxic dissolved compounds. The decay process, stimulated by pulsed electron beams from 50 to 3200 pulses, proceeded intensively in aqueous solutions with the addition of crystal violet or bisphenol A. Some of the transformation products were emitted into the air, changing the composition and intensity of its luminescence. The conversion of the studied compounds was carried out using electron absorption spectroscopy and stationary fluorescence.
