Features of the Photodegradation of 2,4-Dichlorophenoxyacetic Acid Under the Influence of Radiation from KrCl Excilamps

The herbicide 2,4-dichlorophenoxyacetic acid was investigated in aqueous solution. A KrCl excilamp with an emission wavelength of 222 nm was used as radiation source. The direction of variation in the concentration of the toxicant during UV irradiation is discussed. The photodegradation constants ar...

More Information
Summary:The herbicide 2,4-dichlorophenoxyacetic acid was investigated in aqueous solution. A KrCl excilamp with an emission wavelength of 222 nm was used as radiation source. The direction of variation in the concentration of the toxicant during UV irradiation is discussed. The photodegradation constants are calculated. A chromatographic-mass spectrometric analysis of the photoproducts was undertaken.
