Khwarizmi Engineering at the University of Baghdad obtained a patent entitled ((Green synthesis of zinc-ferrite nanoparticles (ZnF-NPs) using eucalyptus extract)). The Chairman of the Editorial Board of Al-Khwarizmi Engineering Magazine and the representative of the teaching staff and the Academics Syndicate, Dr. Muhammad Abd Attia Al-Sarraj, and the lecturer in the Department of Biochemical Engineering with the master’s student researcher Zahraa Aqeel Najm obtained a new patent from the Central Organization for Standardization and Quality Control. The patent included green synthesis (a highly cultivated plant in Iraq) as a reducing agent.
Green synthesis is another environmentally friendly approach that avoids the use of harmful chemicals due to its low cost and great efficiency for large-scale industrial production. So the green industrial method is a new method that can be applied to the synthesis of nanoparticles in the field of nanotechnology to process organic pollutants using zinc ferrite particles manufactured by the green method. UV-A lamps were also used as a source of radiation inside the reactor. To find out the factors affecting the removal process and obtain the best conditions in the batch system, the removal of the dye was studied under the influence of several transactions.
The analysis of the results by BBD showed that the dye was completely decomposed within 60 minutes at pH 7, the dye concentration is 5mg/L and the intensity of UV rays is 24 W/m2. While in the continuous system, the removal efficiency of 71% was obtained at the dye concentration of 34.3136 mg/L, the flow rate is 3.72753mL/min, the catalyst height is 0.966 cm, and the radiation intensity is 18 W/m2.
