Photocatalytic Degradation of an Anionic Surfactant by Tio2 Nanoparticle under UV Radiation in Aqueous Solutions
In this paper the photocatalytic degradation of the anionic surfactant, linear alkylbenzene sulfonicacid (LABSA) was investigated using UV radiation in the presence of TiO2. Our findingsdemonstrate that various parameters exert their individual influence on the photocatalytic degradationof surfactant in wastewaters. The mentioned parameters have been categorized as follow: the initialpH of the ...
متن کاملPhotochemical 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 کاملStudy of Photooxidative Degradation of Reactive Dyes from Aqueous Solutions by UV/ C102 Process
The color removal of three reactive dyes in an aquatic system without priortreatment was studied. Selected commercial dyes were treated with NaC102 andUV as oxidation agents. Effects of nature of oxidant, temperature, pH ofsolutions, concentration of C107—, contact time of C102— and UV irradiation wereinvestigated. Optimal C102— concentration for color removal in the absence of UVirradiation wa...
متن کاملPhotocatalytic Degradation of Humic Acid by Ag/ZnO Nanoparticles under UVC Irradiation from Aqueous Solutions
Introduction: Humic acid (HA) is one the original disinfection byproducts processors in water treatment. So, removing it is necessary before water chlorination. In the present study, photodegredation of humic acid in water using Ag/ZnO nano particle under UVc irradiation in batch system was investigated. Material and Methods: Photocatalytic study was carried out to evaluate the effect of UVc (...
متن کاملSonocatalytic degradation of p-chlorophenol by nanoscale zero-valent copper activated persulfate under US irradiation in aqueous solutions
In this study, nanoscale zero-valent copper (nZVC) as catalyst activated persulfate (PS) was used for the degradation of p-chlorophenol (p-CP) under ultrasonic (US) irradiation in aqueous solution. The effect of different operational parameters such as solution pH (3.5-10.5), PS concentration (1-7.5 mm/L), nZVC dosage (5-35 mg/L) and initial p-CP concentration (10-100 mg/L) were evaluated at di...
