Photocatalytic Degradation of Anthracene in Closed System Reactor

Abstract

Polycyclic aromatic hydrocarbons (PAHs) represent a large class of persistent organic pollutants in an environment of special concern because they have carcinogenic and mutagenic activity. In this paper, we focus on and discuss the effect of different parameters, for instance, initial concentration of Anthracene, temperature, and light intensity, on the degradation rate. These parameters were adjusted at pH 6.8 in the presence of the semiconductor materials (TiO2) as photocatalysts over UV light. The main product of Anthracene photodegradation is 9,10-Anthraquinone which isidentified and compared with the standard compound by GC-MS. Our results indicate that the optimum conditions for the best rate of degradation are 25 ppm concentration of Anthracene, regulating the reaction vessel at 308.15 K and 2.5 mW/cm2of light intensity at 175 mg/100 mL of titanium dioxide (P25).

Preparation, Characterization, and Photocatalytic Applications of MWCNTs/TiO2Composite

“…Titanium dioxide (TiO 2 ) is photocatalyst material using light to destroy environmental contaminants from wastewater due to its ability to convert them into innocuous end products such as CO 2 and H 2 O [1]. TiO 2 is one of the most prominent oxide semiconductor materials due to its high photocatalytic activity, chemical stability, nontoxicity, physical properties, and low cost [2]. However, TiO 2 has some disadvantage such as low surface area and easy recombination of the electron-hole pair [3].…”

Kinetic Study for Reduced the Toxicity of Textile Dyes (Reactive yellow 14 dye and Reactive green dye) Using UV-A light/ZnO System

“…Several routs were followed to remove of these dyes by multi methods as example by extraction techniques, sorption by natural and synthesized surfaces, coagulation the dyes, filtration the polluted water and by advances oxidation processes (AOPs) [9][10][11][12]. In recent years methods of AOPs were applied to remove of pollutants from waste water [13,14]. Treatment of pollutants by AOPs most likely combined with using heterogeneous semiconductor in presence of photo.…”

Physical-Chemical Study of Anthracene Selective Oxidation by a Fe(III)-Phenylporhyrin Derivative

“…Furthermore, the formation of nitro-anthracene from the degradation of anthracene by the OH • and NO3 • has been investigated using quantum chemical calculations [22,23]. Karan et al reported the photocatalytic degradation of anthracene under UV irradiation on TiO2 nanoparticles, they found that the main product of oxidation of Anthracene is 9,10-Anthraquinone, which is safer for the environment than Anthracene [24]. Kozak et al removed PAHs from the pretreated coking wastewater by using CaO2, Fenton reagent under UV irradiation [25].…”
