Degradation of 2-Chlorophenol from Wastewater Using γ-Fe2O3 Nanoparticles
In this study, magnetic nanoparticles (γ-Fe2O3) were used for the degradation of 2-chlorophenol (CP) from wastewater. The size of these magnetic nanoparticles was measured using XRD and found to be about
متن کاملDirect amine-functionalisation of γ-Fe2O3 nanoparticles.
A novel and simple preparation of amine-modified γ-Fe2O3 nanoparticles is described. The presence of amine groups on the surface, instead of hydroxyl groups, will allow conjugation of biologically active molecules to the iron oxide nanoparticles without the need for a size increasing silica shell. Furthermore, the outer amine-layer increases the temperature of the γ-Fe2O3 to α-Fe2O3 structural ...

متن کاملFluoride adsorption on γ − Fe2O3 nanoparticles
BACKGROUND Fluoride contamination of groundwater, both anthropogenic and natural, is a major problem worldwide and hence its removal attracted much attention to have clean aquatic systems. In the present work, removal of fluoride ions from drinking water tested using synthesized γ-Fe2O3 nanoparticles. METHODS Nanoparticles were synthesized in co-precipitation method. The prepared particles we...
متن کاملMagnetic γ-Fe2O3, Fe3O4, and Fe nanoparticles confined within ordered mesoporous carbons as efficient microwave absorbers.
A series of magnetic γ-Fe2O3, Fe3O4, and Fe nanoparticles have been successfully introduced into the mesochannels of ordered mesoporous carbons by the combination of the impregnation of iron salt precursors and then in situ hydrolysis, pyrolysis and reduction processes. The magnetic nanoparticles are uniformly dispersed and confined within the mesopores of mesoporous carbons. Although the as-pr...
