Dual Valorization of Olive Mill Wastewater by Bio‐Nanosynthesis of Magnesium Oxide and Yarrowia lipolytica Biomass Production

“…The absorp- In the MgO NPs spectra, the broad absorption peaks at 3399 cm À 1 and 1637 cm À 1 are respectively due to the stretching and the bending vibration of OÀ H. The peak at 658 cm À 1 is assigned to the MgÀ O stretching vibration in Mg(OH) 2 . [26] The absorption peaks at 1416 and 1560 cm À 1 are assigned to the bending vibration of OH on the surface of MgO NPs.…”

“…[16] Many physico-chemical methods were developed for the synthesis of MgO NPs including thermal decomposition, [17] sol-gel, [18] chemical precipitation/aqueous wet chemical, [19] surfactant, [20] flame spray pyrolysis, [21] hydrothermal/ solvothermal, [22] chemical gas phase deposition, [23] laser ablation, [24] hot-melt extrusion, [25] and microwave-assisted method, etc. [26] In addition, most of these pathways suffer from the persistence of some toxic chemical reagents adsorbed on the surface of MgO NPs, which may cause harmful effects in medical applications. [27] In this work, it was found interesting to utilize the biosynthesis method for the preparation of magnesium oxide nanoparticles by using the polyphenols recovered from olive mill wastewater.…”

Bimetallic nickel-ferrite nanorod particles: greener synthesis using rosemary and its biomedical efficiency

“…Hydrazine hydrate is toxic to humans [35]. Current mentioned chemical methods usually have disadvantages such as dependence on expensive equipment, high energy consumption and dependence on chemical compounds toxic to the environment and humans [36][37][38][39][40][41][42][43]. Therefore, finding simple, economical, inexpensive, non-toxic and environmentally friendly methods are very important and necessary for the synthesis of these types of NP.…”

Photo-Fenton like Catalyst System: Activated Carbon/CoFe2O4 Nanocomposite for Reactive Dye Removal from Textile Wastewater

“…Environmental pollution generated by industrial wastewater is one of the greatest problems the world is facing today and dyes are widely applied in many industries, such as leather, textile, plastics, paper, and other entities emanating from pharmaceutical and food industries [1][2][3][4][5]. Dyes effect the photosynthetic activities of aquatic lives and their ensuing byproducts are not biodegradable but are stable, carcinogenic, and hazardous to human health [6][7][8]. Dyes are usually classified on the basis of their chemical structure, such as anionic, cationic, and non-ionic [9,10]; reactive dyes are stable and anionic in character, and display resistance towards light [11,12].…”
