Riboflavin sensitized photodegradation of Furaneol in a β-cyclodextrin complex
(Elsevier Science SA, 2021-04-15)
A study on the photodegradation of the widely employed flavoring compound Furaneol (FUR), in the presence of vitamin B2 (Riboflavin, Rf) was carried out, in aqueous and microheterogeneous media. The system as a whole allows ...
Photodegradation of herbicide Metsulfuron-methyl with TiO2 supported on magnetite particles coated with SiO2
(Elsevier, 2018-12)
Natural watercourses may be significantly contaminated due to the increase of agricultural activities, making it necessary to develop new methodologies for the remediation of agrochemicals, including herbicides. To this ...
Sunlight and UVC-254 irradiation induced photodegradation of organophosphorus pesticide dichlorvos in aqueous matrices
(Elsevier, 2019-02-01)
Dichlorvos (DDVP) is an organophosphorus pesticide that has been classified as highly hazardous chemical by the World Health organization. In this study, the fate of the pesticide DDVP in natural water compartments was ...
Photocatalytic degradation of acridine dyes using anatase and rutile TiO2
(Academic Press Ltd - Elsevier Science Ltd, 2012-06)
The adsorption and photodegradation of acridine orange (AO) and acriflavine (AF) dyes on two mesoporous titania crystalline phases, anatase and rutile, were experimentally studied. Anatase and rutile were characterized by ...
A new fluorescent assay for enalapril maleate
(Springer/Plenum Publishers, 2005-09)
A new spectrofluorimetric method for the enalapril maleate monitoring was studied. Enalapril maleate was found to be highly photolabile. This drug was evaluated according to photodegradation assay at pH 2.5 and 6. Enalapril ...
Has water limited our imagination for aridland biogeochemistry?
(Elsevier Science London, 2011-05)
The classic ecological paradigm for deserts, that all processes are controlled by water availability, has limited our imagination for exploring other controls on the cycling of carbon and nutrients in aridland ecosystems. ...
Remotion of the antibiotic tetracycline by titania and titania-silica composed materials
(Elsevier Science, 2011-09)
Removal of the antibiotic tetracycline (TC) by TiO 2 and the mesoporous binary system TiO 2-SiO 2 have been studied in batch experiments by performing adsorption isotherms/kinetics and photodegradation kinetics under ...
Preparation, characterization and photoactivity of TiO2 obtained by a reverse microemulsion route
(Elsevier Science Sa, 2011-10-17)
TiO2 was synthesized by a reverse microemulsion route. By using different water contents in the reverse microemulsion, we obtained three different materials named R=10, R=20 and R=30. The reverse microemulsion synthesis ...
Photolysis of chlorpyrifos-methyl, chlorpyrifos-methyl oxon, and 3,5,6-trichloro-2-pyridinol
(John Wiley & Sons Ltd, 2019-04)
The photodegradation of chlorpyrifos-methyl (1), and two of its photodegradation products, chlorpyrifos-methyl oxon (2), and 3,5,6-trichloro-2-pyridinol (3) was studied using low pressure Hg lamps irradiating at 254 nm ...
Gum arabic microcapsules as protectors of the photoinduced degradation of riboflavin in whole milk
(American Dairy Science Association, 2014-06)
Microcapsules (MC) made with gum arabic (GA) as shell material without and with b-carotene (bc) as core material were prepared by the spray-drying technique. The effect of these MC on the photodegradation of riboflavin ...
