Chitosan-based ferrimagnetic membrane

A chitosan-based ferrimagnetic membrane (Chitosan/NiFe 2O 4) was prepared and it showed a typical magnetization of soft ferrimagnetic material with M s=16 emu/g at 50 kOe and a high capacity to extract Hg(II), Cu(II) and Zn(II) ions from aqueous solutions. These results indicate that the Chitosan/Ni...

Description
Summary:A chitosan-based ferrimagnetic membrane (Chitosan/NiFe 2O 4) was prepared and it showed a typical magnetization of soft ferrimagnetic material with M s=16 emu/g at 50 kOe and a high capacity to extract Hg(II), Cu(II) and Zn(II) ions from aqueous solutions. These results indicate that the Chitosan/NiFe 2O 4 is a good candidate to remove heavy metals from polluted water with the possibility that its recovery can be done by an electromagnet.
