Electron beam induced transformations of phenol in water in the presence of humic substances

Electron beams of a RADAN-type pulse accelerator with an average energy of 170 keV and a pulsed cathodoluminescence spectrum meter in the range from 350 to 900 nm, as well as the recording of absorption and fluorescence spectra were used to study the transformation of phenol in water in the presence of humic substances. With the help of this beam, cathodoluminescence excitation and radiolysis action on an aqueous solution of phenol were simultaneously carried out. The degree of transformation of the studied substances was determined by analyzing the luminescence and absorption spectra of the irradiated solution. A study of the effect of a pulsed electron beam on an aqueous solution of phenol in the presence of humic substances showed that the efficiency of phenol transformation in the presence of a sample of a mixture of humic and fulvic acids increases by 2.6 times compared to an aqueous solution.
