Abstract In this study, the Fenton/adsorption of dye effluent containing Levafix blue has been carried out via a cost-efficient and eco-friendly heterogeneous Fenton solar-Fenton methods. Alum sludge, water treatment by-product were successfully collected calcined to 400 °C (AS400) tested for use as catalyst in process. X-ray diffraction, Scanned electron microscopy techniques applied investiga...
Background: Pharmaceuticals have arisen as emerging environmental pollutants due to their potential impact on humans, animals and microorganisms even at low concentrations. Conventional wastewater treatment plants are known to be ineffective for removal of many pharmaceuticals present in wastewater. Advanced oxidation processes are one of the most promising treatment technologies for degradatio...
Background: Mature landfill leachate is a complicated mixture which is resistant to biological treatment processes. The treatment of mature landfill leachate by struvite precipitation and Fenton oxidation was the main objective of the current research. Methods: Struvite with the phosphate/ammonia/magnesium molar ratio of 1/1/1.05 was considered during all experiments. Five initial pHs of 3, 4, ...
In order to see the influence of different variable parameters (initial pH of the solution, Fe++ concentration and H2O2 concentration) and the efficiency to remove Malachite Green dye (Basic Green 4) from aqueous solution, Fenton Oxidation method was employed. Then different parameters were studied using known concentration (150 mg/l) and initial COD (256 mg/l) of prepared dye synthetic solutio...
diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. it was related to toxicity for aquatic organisms, animals, and humans. waters contaminated with such persistent insecticides should be treated with suitable treatment processes. in this research, diazinon removal from aqueous solutions by the photo–fenton–like process (uv/h2o2/fe0) was investigated. this e...
A highly active heterogeneous Fenton catalyst was fabricated by impregnating iron oxide nanoparticles in alumina coated mesoporous SBA-15 silica.
