Инноватика-2021 : сборник материалов XVII Международной школы-конференции студентов, аспирантов и молодых ученых, 22-23 апреля 2021 г., г. Томск, Россия С. 39-44Abstract: In this work, the phototransformation of bisphenol A (BPA) was investigated by electron spectroscopy and fluorescence in the presence of polypropylene superfine microfibers (PPM) under the action of KrCl excilamp radiation. With an increase in the irradiation time from 0 to 10 minutes, effective photodegradation of the initial toxicant occurs and a photoproduct is formed, which fluoresces in the region of 405÷410 nm. It was observed that the intensity of the emission band after 60 minutes of irradiation in the presence of samples No. 210, No. 325, No. 340 and No. 425 is less than for the other samples. This may be due to the fact that BPA and photoproducts are adsorbed on the surface of the PPM
