Research of the phototransformation of bisphenol A in the presence of materials based on ultrafine polypropylene fibers
The effect of UV radiation on the efficiency phototransformation BPA in water in the presence of polypropylene nonwoven based on ultrafine fibers. The absorption and fluorescence spectra of the investigated substance with types of fibers of various properties were obtained. After excitation with an excilamp, the main photoproduct BPA fluoresces in the region of ~408 nm. With an increase in the irradiation time from 0 to 10 minutes, the fluorescence intensity of this photoproduct increases. The absorption and fluorescence spectra of cyclohexane containing desorbed compounds from the fiber surface indicate the adsorption of a photoproduct on its surface during UV irradiation.
