| Abstract Scope |
Magnetic filtration can provide rapid, efficient removal of magnetic materials from a waste stream. However, since most pollutants are non-magnetic, it is necessary to use magnetically-active “extractants” to bind to pollutants and allow their separation by a magnetic filter. Excellent candidates for extractants are nanoparticles of magnetic ceramic oxides such as ferrites and magnetite whose surfaces have been derivitized to provide binding sites for toxic metal ions or organic pollutants. Such materials can be used to separate petrochemicals from water, break oil in water emulsions, and remove heavy or radioactive metal ions from waste streams. This paper will discuss the removal of 4,6-dinitro-o-cresol pesticide from aqueous solutions via magnetic filtration using octanoate and stearate capped magnetite and nickel ferrite nanoparticles. |
