Abstract
Methods and compositions for removing a contaminant from its environment. The method includes forming a magnetic composition comprising the contaminant and an amphiphilic substance, and applying a magnetic field to the magnetic composition so as to separate the magnetic composition from the environment. One composition includes a micelle array confined in a magnetic mesoporous framework. Another composition is formed by adhering an amphiphilic material comprising functional surface groups to a contaminant, then interacting a magnetic material with the functional surface groups of the amphiphilic material. In various versions, the contaminant can be a hydrophobic organic compound, or a fullerene-related nanoparticle. The methods can also be used to purify hydrophobic organic compounds or fullerene-related nanoparticles.
