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 this study, we aimed to systematically optimize the operating parameters in degradation and mineralization of tetracycline by Fenton process. For purpose; optimum values were found for Fe2+ concentration, H2O2 concentration pH, reaction time, sedimentation times which are effective study where initial was used as 100 mg/L; 4 30 mg/L 10 min time 90 time. Under these conditions, TC 100%, while...

Fe2V4O13 is prepared and characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV-diffuse reflectance spectroscopy (UV-DRS), high resolution scanning electron microscopy (HR-SEM) using energy dispersive X-ray spectroscopy (EDX) analysis. The hetero-Fenton catalyst can be used to mineralize Methyl Orange (MO) under UV-A light. The mineralization rate is influenced by hydr...

The catalytic capability of original carbon nitride (CN) is limited by a small specific surface area and high electron–hole recombination rate. In this study, WO3-loaded porous nanosheets (MCA-CN/WO3) were synthesized thermal treatment with melamine, cyanuric acid WCl6. MCA-CN/WO3 could degrade 98% the methylene blue (MB) within 30 min in photo-Fenton-like process, displaying better activity th...

Abstract The demand for clean water free of pollution has become an urgent priority humanity. Gd 2 Zr O 7 nanoparticles were successfully synthesized via sol–gel auto combustion as a type pyrochlore to be used in the dye phytoremediation using Fenton-like approach. have been prepared auto-combustion strategy. annealing process was performed furnace at 1100 °C h form defect-fluorite structured w...

The phytochemicals present in the grapes are responsible for nutraceutical and health benfits due to their antioxidant properties. These phytochemicals, however, vary greatly among different cultivars. In this study, we evaluated the antioxidant potential and protective role of four different Indian grape (Vitis vinifera) cultivars extracts, namely Flame seedless (Black grapes), Kishmish chorni...
