Atmospheric photodegradation of ethyl vinyl ketone and vinyl propionate initiated by OH radicals
(Elsevier Science, 2011-01)
Rate coefficients for the reactions of hydroxyl radicals with ethyl vinyl ketone and vinyl propionate were determined at 298 K and atmospheric pressure. A collapsible chamber with gas chromatography was used to perform ...
Titania hollow spheres modified with tungstophosphoric acid with enhanced visible light absorption for the photodegradation of 4-chlorophenol
(Royal Society of Chemistry, 2017-02)
Titania hollow spheres were synthesized using silica nanospheres as the template. The core was removed using NaOH solution. They were subsequently impregnated with tungstophosphoric acid (TPA) solutions and annealed at two ...
Stability of flavonoids in the presence of riboflavin-photogenerated reactive oxygen species: A kinetic and mechanistic study on quercetin, morin and rutin
(Wiley Blackwell Publishing, Inc, 2010-07-07)
Kinetic and mechanistic aspects on the stability of the flavones (FL) quercetin (Que), morin (Mor) and rutin (Rut), in methanolic solution and in the presence of reactive oxygen species (ROS) generated by visible light-promoted ...
Visible light-mediated photodegradation of imidazoline drugs in the presence of Riboflavin: Possible undesired effects on imidazoline-based eye drops
(Elsevier Science Sa, 2017-01)
The imidazoline-based ophthalmic drugs oxymetazoline and xylometazoline are widely used as ocular decongestants in pharmaceutical preparations. In this paper, the degradation of these drugs and the model compound ...
Reactive oxygen species-mediated degradation of antidiabetic compounds: Cytotoxic implications of their photodegradation products
(Wiley Blackwell Publishing, Inc, 2018-11)
Reactive oxygen species (ROS) have been described in their double physiological function, helping in the maintenance of health as well as contributing to oxidative stress. Diabetes mellitus is a chronical disease nearly ...
Comparative study of ZnO thin films doped with transition metals (Cu and Co) for methylene blue photodegradation under visible irradiation
(MDPI AG, 2020-05)
We synthesized and characterized both Co-doped ZnO (ZnO:Co) and Cu-doped ZnO (ZnO:Cu) thin films. The catalysts’ synthesis was carried out by the sol–gel method while the doctor blade technique was used for thin film ...
Degradation of anti-inflammatory drug diclofenacusing cobalt ferrite as photocatalyst
(Institution of Chemical Engineers, 2021-02)
Emerging pollutants, among them pharmaceutical compounds, are found in surface and ground waters, suggesting their ineffective removal by conventional wastewater treatment technologies. In this paper, the removal of sodium ...
Bioallethrin degradation by photo-Fenton process in acetonitrile/water and aqueous β-cyclodextrin solutions
(Elsevier Science Sa, 2018-10-01)
Bioallethrin (Bio) is an insecticide that chemically and functionally belongs to the family of the synthetic insecticides named pyrethroids. In this work the degradation of Bio is studied by the photo-Fenton and ...
Understanding the photodegradation mechanism of gaseous acetaldehyde over Bi2Wo6 – modified ZnWo4 photocatalyst under uv light irradiationПонимание механизма фотоградации газообразного ацетальдегида над znwo4 фотокатализатором, модифицированным Bi2Wo6 под уф облучениемGazsimon atsetaldegidni bi2wo6 tomonidan modifikatsiyalangan ZnWo4 fotokatalizi orqali uv nurlanish ostida fotokatalitik parchalanish mexanizmini o’rganish
(Ministry of higher and secondary specialized education of the Republic of Uzbekistan, 2021-03)
Indoor air quality has a significant impact on human health as people spend more time indoors. As a common indoor air pollutant, acetaldehyde is considered toxic when exposed to it for a prolonged period. The aim of this ...
Photo-fenton and riboflavin-photosensitized processes of the isoxaflutole herbicide
(Wiley Blackwell Publishing, Inc, 2019-05)
The proherbicide Isoxaflutole (IXF) hydrolyzes spontaneously to diketonitrile (DKN) a phytotoxic compound with herbicidal activity. In this work, the sensitized degradation of IXF using Riboflavin (Rf), a typical environmentally ...
