Study 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 کاملRemoval of natural organic matter from aqueous solutions by electrocoagulation
Natural organic matter (NOM) affects some qualitative parameters of water such as color. In addition, it can deteriorate the performance of water treatment process including coagulation, adsorption, and membranes. NOM also reacts with chlorine in the chlorination process and may form disinfection by-products. The present study was carried out in laboratory-scale in a batch system using a cylind...
متن کاملCharacterization of Fe3O4/rGO Composites from Natural Sources: Application for Dyes Color Degradation in Aqueous Solution
The magnetite (Fe3O4) nanoparticle and graphene oxide (GO) have become interesting materials due to their advanced applications. In this work, we investigated the fabrication of Fe3O4 nanoparticles (NPs) from iron sands and reduced graphene oxide (rGO) NPs from natural graphite. The core-shell fabrication of the Fe3O4/rGO was co...

متن کاملFabrication Fe3O4/SiO2/TiO2 Nanocomposites and Degradation of Rhodamine B Dyes under UV Light Irradiation
Recycling and reusing of catalyst is an important factor to produce capable and low cast catalysts. Silica coated magnetic nanoparticles (Fe3O4/SiO2) were synthesized via a simple sol-gel method with the aid of sonication. Fe3O4 nanoparticles. After that a layer of TiO2 was constricted by hydrolyze and condensation of Teteranormalbuthyltitanate to produce Fe3O4/SiO2/TiO2 nanocompsite. As-synthe...
