Abstract

Nanoparticles of magnetite (Fe3O4) have been successfully synthesized by coprecipitation method by mixing FeSO4.7H2O and FeCl3.6H2O with the addition of 10% NH4OH as kopresipitan. Then, functionalized Fe3O4  concentration variation silica (SiO2) 5%, 10%, 15%, 20%, 30% and 50%. Particle size and magnetic properties of Fe3O4 nanoparticles were tested by X-Ray Diffraction (XRD) and Vibrating Sample Magnetometer (VSM). XRD results showed the addition of silica is not found new phases when added SiO2that serves as a template. The particle size of Fe3O4 nanoparticles obtained 14.23 nm, while the Fe3O4nanoparticles with the addition of a concentration of 5% and 20% respectively SiO215.45 nm and 16.37 nm. VSM results show the value of saturation magnetization and remanent magnetization decreased as more silica concentration, and increased coercivity field. Test Results of Fourier Transform Infra Red (FTIR) obtained new peaks which indicate that the functionalization process Fe3O4 with silica has been successfully carried out.

Abstract

Magnetite (Fe3O4) nanoparticles have been successfully synthesized using co-precipitation method and have been used for removing Cu, Mn and Ni metals ions from artificial wastewater. Ability of removing metal ions with Fe3O4 against pH, adsorbent particle size, readsorption and by addition of Polyethylene Glycol (PEG-4000) as coating agent of adsorbent have been studied. The adsorption process was found to be pH-dependent. Maximum adsorption at pH 12 for most of the metal ions with percent of sorption Cu 99.79%, Ni 69.83% and Mn 44.53%. Using adsorbent with 12 nm of particles size, readsorption process and by addition of Polyethylene Glycol (PEG-4000) as coating agent of adsorbent also made the ability of removing metals ions increasing. Preliminary results indicate that magnetite nanoparticles may be used as an adsorbent for removal of Cu, Mn and Ni from wastewater.

Abstract

Nanocrystalline mixed spinel ferrite of Co0.5Ni0.5Fe2O4 magnetic nanoparticles (MNPs) has been successfully synthesized by coprecipitation method and encapsulated by PEG-4000 with various concentrations. X-Ray Diffraction (XRD) patterns showed that nanoparticles contained Co0.5Ni0.5Fe2O4 spinel ferrite with crystallite size of 14.9 nm. After PEG-4000 encapsulation particles size decreased became 7.7 nm. Interaction Co0.5Ni0.5Fe2O4 nanoparticles with long chain PEG-4000 caused the crystal growth trap. Lattice parameter and X-Ray density have no significant difference after encapsulated PEG-4000. The coercivity (??) of Co0.5Ni0.5Fe2O4 was 214 Oe. The ?? decreased after PEG-4000 encapsulation became 127 Oe, which is due to the decrease of crystallite size. The maximum magnetization (Mmax) of Co0.5Ni0.5Fe2O4 was 12.0 emu/g, and decreased after PEG-4000 encapsulation to 11.7 emu/g, because PEG-4000 is paramagnetic. After the concentration of PEG-4000 increased, then the amount of paramagnetic material increase which lead maximum magnetization decrease.
