Photochemical Degradation of 2,4-dichlorophenol in Aqueous Solutions by Fe2+/ Peroxydisulfate/ UV Process
Phenol and its derivatives are one of the most common contaminants in the aquatic ecosystem. Because of high toxicity of 2,4-DCP for aquatic life, resistance to biodegradation and potential for biological accumulation it is known as a priority contaminant in the aquatic environment. Advanced Oxidation Processes were successfully used for degradation of non-biodegradable contaminants that are re...
متن کاملTopical Administration of Manuka Oil Prevents UV-B Irradiation-Induced Cutaneous Photoaging in Mice
Manuka tree is indigenous to New Zealand, and its essential oil has been used as a traditional medicine to treat wounds, fever, and pain. Although there is a growing interest in the use of manuka oil for antiaging skin care products, little is known about its bioactivity. Solar ultraviolet (UV) radiation is the primary environmental factor causing skin damage and consequently premature aging. T...
متن کاملGarlic Supplementation Ameliorates UV-Induced Photoaging in Hairless Mice by Regulating Antioxidative Activity and MMPs Expression.
UV exposure is associated with oxidative stress and is the primary factor in skin photoaging. UV-induced reactive oxygen species (ROS) cause the up-regulation of metalloproteinase (MMPs) and the degradation of dermal collagen and elastic fibers. Garlic and its components have been reported to exert antioxidative effects. The present study investigated the protective effect of garlic on UV-induc...
متن کاملSequential UV-biological degradation of chlorophenols.
The sequential UV-biological degradation of a mixture of 4-chlorophenol (CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and pentachlorophenol (PCP) was first tested with each pollutant supplied at an initial concentration of 50 mg l(-1). Under these conditions, the chlorophenols were photodegraded in the following order of removal rate: PCP>TCP>DCP>CP with only CP and DCP remaining...
متن کاملImmobilization of cobalt doped rutile TiO2 on carbon nanotubes walls for efficient photodegradation of 2,4-dichlorophenol under visible light
In this work, we focused on improvement of rutile-type TiO2 degradation efficiency by cobalt doping and decorating on carbon nanotubes walls (CNTs) (Co-TiO2/CNTs). We also synthesized pure TiO2, Co-TiO2 and TiO2/CNTs samples for control experiments. The textural and morphology features of the samples were characterized by a range of analyses including: XRD, FESEM/EDX. FTIR, TEM, UV-Vis DRS and ...
