Optimizing and control of effective synthesize parameters for Fe3O4 nanoparticles using response surface methodology
Ba-Abbad, Muneer M.; Chai, P. V.; Benamour, Abdelbaki; Ewis, Dina; Mohammad, Abdul Wahab; Mahmoudi, Ebrahim... more authors ... less authors ( Springer Science and Business Media Deutschland GmbH , 2022 , Article)To control Fe3O4 nanoparticles (Fe3O4 NPs) size, different molar ratio of Fe2+ and Fe3+ as well as ammonium hydroxide (pH) was used to synthesize Fe3O4 NPs through co-precipitation method. The Box–Behnken design was selected ... -
Synthesis of Fe3O4 Nanoparticles with Different Shapes Through a Co-Precipitation Method and Their Application
Ba-Abbad, Muneer M.; Benamour, Abdelbaki; Ewis, Dina; Mohammad, Abdul Wahab; Mahmoudi, Ebrahim ( Springer , 2022 , Article)Magnetic Fe3O4 nanoparticles (NPs) were successfully synthesized via co-precipitation method using ferric chloride and ferrous sulphate as the starting materials. The shape and the size of Fe3O4 NPs were controlled by using ...
