A solvent thermal method which depends on a thermal process under critical temperature and pressure was used to prepare cobalt iron oxide magnetic nanoparticles with a molar ratio 2. The prepared particles were in the form of nanoparticles with diameter ranging from 5 to 10 nm and with amorphous structure. Magnetic hysteresis behavior with saturation magnetization 36.31 emu/g and coercivity 4 Oe were observed for the nanoparticles. Polyvinyl alcohol was loaded with different concentrations of cobalt iron oxide nanoparticles using casting technique. Hysteresis loops for the polymer films were observed and both the saturation magnetization and coercivity were increased from 0.36 to 16.03 emu/g and 115 to 293 Oe for samples containing 5 and 20 wt% of nanoparticles, respectively. The elastic modulus of films was increased from 2.7 to 4.9 GPa for unloaded and loaded samples with 20 wt%, respectively. The storage modulus of the polymer films was found to obey the percolation behavior.

Immobilized microbe technologies are expected to be effectively used in wastewater treatment. Removal of heavy-metals from wastewater by immobilized Phanerochaete chrysosporium (Pc) with Ca-alginate and iron oxide magnetic nanoparticles (MNPs) was studied. The results showed that a biosorbent as Pc immobilized by Ca-alginate and iron oxide magnetic nanoparticles was successfully developed. And the iron oxide magnetic nanoparticles played an important role in the increase of biosorption capacity of Pc. Energy dispersive spectrometer (EDS) analysis confirmed that metal ions adsorbed to the surface of the biosorbents were partly transmitted to the interior of biosorbents, mainly embedded with iron oxide nanoparticles and Ca-alginate. Moreover, it was found that MNPs-Ca-alginate immobilized Pc showed a good affinity to various heavy metals, such as Pb(II), Zn(II), Cd(II) or Mg(II) and so on. The results proved the high efficiency of the biosorbents for heavy-metal removal and its potential application in the treatment of metal-containing wastewater.
