In this work, orthoferrite NdFeO3 nanomaterials with particle sizes 20-40 nm have been successfully synthesized via a simple co-precipitation method through the hydrolysis of Nd (III) and Fe cations in hot water 5% NaOH as precipitating agent. Single-phase was generated after calcination as-prepared powder at 700, 800, 900 °C for 1 hour. The UV-Vis spectra room temperature presented strong abso...
Background and purpose: The aim of this study was to investigate the efficiency of Fe3O4 nanoparticles synthesized by the chemical co-precipitation method for removal of black acid 1 from aquatic solutions. Materials and methods: In an experimental study, the Fe3O4 nanoparticle was synthesized by the chemical co-precipitation method using Fe+2 and Fe+3 solution in the presence of N2. The eff...
The aim of the present study was to prepare nano-sized calcium fluoride (CaF2). Calcium fluoride nanoparticles were synthesized by CaCl2.6H2O and ammonium fluoride. Nanoparticles were synthesized by co-precipitation method. The synthesized nanocrystals were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electro...
