A | Tchaikovskaya, Olga N | Mayer, Georgy V, 1948- | Sokolova, Irina VMaterial type: ArticleArticleSubject(s): гуминовые кислоты | спектроскопия | фотохимия | флуоресценция | фотодеградацияGenre/Form: статьи в журналах Online resources: Click here to access online In: Proceedings of SPIE Vol. 10614 : XIII International conference on atomic and molecular pulsed lasers, September 10-15, 2017, Tomsk, Russia. P. 106140F-1-106140F-4Abstract: Spectroscopy and photochemistry of humic acids are discussed. The samples of HAs fractions were obtained from Fluka Chemical Co and prepared from peat of Western Siberia region. The comparative analysis of these acids with the sample of humic acids allocated from brown coal is carried out. A specific feature of the reactor is the use of barrier discharge excilamp (KrCl) with radiation wavelength λ = 222 nm. Influence of the received humic acids on process of photodegradation of herbicide - 2.4-dichlorophenoxyacetic acid is considered.
