Abstract

Magnetic flocculants are synthesized from magnetite (Fe3O4) nanoparticles and ionic and nonionic acrylamide copolymers having different concentrations of ionic units and molecular weights. The synthesis is carried out in two steps: two magnetite samples having different size and surface characteristics are precipitated with ammonia from a mixed aqueous solution of Fe(II) and Fe(III) chlorides; then, the obtained samples are mixed with aqueous solutions of polyacrylamide flocculants. Individual particles of magnetite, copolymers, and magnetic flocculants based thereon are characterized by dynamic light scattering. Effect of the nature and flocculating ability of magnetic flocculants on the process of sedimentation of a titanium dioxide suspension is estimated. Varying the sizes of magnetic nanoparticles and the molecular parameters of acrylamide copolymers in the magnetic flocculant makes it possible to obtain a highly efficient multifunctional flocculant for the selective separation of multicomponent disperse systems.
