Summary:Title screen
Using electronic spectroscopy and fluorescence techniques, the degradation of 2-methyl-4-chlorophenoxyacetic acid has been researched in water under the excitation with UV radiation produced by a KrCl excimer lamp in the presence of “TiO[2], SnO[2], SnO[2]/TiO[2] Nanoparticles – Polypropylene Fibrous Carrier” Systems. It has been determined that MCPA phototransformation is most efficient when using the “TiO[2]/SnO[2] heteronanoparticles – carrier” system with the concentration of 25/6 mg/g. The results indicate that systems with applied semiconductor particles do not exhibit sorption properties towards МСРА molecules. Therefore, the change in the spectral characteristics of a МСРА water solution after time-exposure and exposure to radiation is only associated with the phototransformations of non-adsorbed МСРА molecules and with the emergence of their photodegradation products.
