  • Title: Functional, mesoporous, superparamagnetic colloidal sorbents for efficient removal of toxic metals.
    Author: Sinha A, Jana NR.
    Journal: Chem Commun (Camb); 2012 Sep 25; 48(74):9272-4. PubMed ID: 22872025.
    Abstract:
    γ-Fe(2)O(3) incorporated mesoporous silica particles of 50-100 nm size have been synthesized which are functionalized with chelating agents of metal ions. These particles are water dispersible but aggregate in response to the external magnetic field and have been used for high performance and selective removal of Cd, Pb, Hg and As.
