Magnetic flocculation for nanoparticle separation and ...

Flocculant polymers were coated onto magnetic nanoparticles (Fe 3 O 4 @SiO 2) to prepare reusable magnetic flocculants (MFs). When added to colloidal nanoparticle dispersions, MFs aggregate with the suspended nanoparticles to form magnetically responsive flocs, which upon separation can be reversibly deflocculated for nanoparticle release, and ...
