چکیده انگلیسی
Sequencing coagulation - photocatalytic degradation using UVA/MgO nanoparticles process was investigated for Acid red 73dye removal and then treatment of a real textile wastewater. Effective operational parameters including pH and coagulant and photocatalyst dosage were studied in synthetic wastewater and then the process was applied for real wastewater. Both coagulation and photocatalytic processes were pH dependent. At coagulant dosage of 200Â mg/L and initial pH of 6, the dye concentration decreased from 200 to 31Â mg/L. Complete removal of AR73 was observed with MgO nanoparticles of 0.8Â g/L, initial pH of 5 and reaction time of 60Â min. Langmuir-Hinshelwood model was well fitted with removal results (R2: 0.939-0.988 for different initial dye concentration). In the case of real textile wastewater, the sequence coagulation-UVA/MgO nanoparticles photocatalytic degradation yielded considerable total COD and TOC removal 98.3% and 86.9%respectively, after 300Â min.
