Photocatalytic degradation of drugs in water mediated by acetylated riboflavin and visible light: A mechanistic study
نویسندگان
چکیده
There is a current concern, among the scientific community, on pollutants classified as “persistent organic (POPs)”. Pharmaceuticals and personal care products (PPCPs) belong to this family of contaminants; therefore, it necessary find more efficient techniques able achieve their removal from environment. This study focuses two different pharmaceuticals: carbamazepine atenolol, chosen for widespread use chemical medical properties. In work, an dye, acetylated riboflavin, has been used in combination with visible light photodegradation these POPs <2 h. Moreover, photophysical experiments demonstrated involvement singlet triplet excited states riboflavin generated oxygen drugs. Besides, detailed UFLC-MS-MS analysis photoproducts confirmed oxidation Finally, plausible mechanism postulated.

In this paper, 2wt.% Fe doped TiO2 nanopowder was prepared by a combination of sol-gel and mechanical alloying methods. The mechanical alloying of Fe powder with Ti(OH)4 gel produced from the sol-gel method was used to produce Fe doped TiO2 nanopowder. The synthesized samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and diffuse reflectan...

In this study, Nitrogen doped TiO2 photocatalysts were prepared by the sol gel method and physicochemical properties were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), photoluminescence, and energy dispersive X-ray spectroscopy (DRS) techniques. The XRD data indicated that the nanoparticles had the same crystals structures as the pure TiO2</su...
متن کاملThe Study of Photocatalytic Degradation Mechanism under Visible Light Irradiation on BiOBr/Ag Nanocomposite
Due to the pollution of dyeing and textile industry wastewaters in different colors and the need to remove these pollutants from the wastewaters, it is necessary to study and develop effective and efficient technology solutions required. To remove dye from aqueous solutions, photodegradation is employed as an effectively simple way. Thus, the BiOBr photocatalyst was chemically made by synthesis...
متن کاملVisible light photocatalytic reduction of aldehydes by Rh(iii)-H: a detailed mechanistic study.
The chemoselective photoreduction of aldehydes in the presence of ketones was achieved using triethanolamine (TEOA) as sacrificial electron donor, proflavine (PF) as photocatalyst and [Cp*Rh(iii)(bpy)Cl]Cl (Rhcat) as mediator. The reducing agent, which reacts with the carbonyl group was found to be [Cp*Rh(iii)(bpy)H]Cl (Rh(iii)-H). Contrary to formate-based reduction, its slow photochemical in ...
