Flocculation of the titanium dioxide suspension (anatase) with compositions from anionic and cationic acrylamide copolymers

Abstract

We have studied the kinetics of flocculation in metered introduction into an aqueous-salt medium of compositions from acrylamide anionic and cationic copolymers in the mode of hindered precipitation on a model disperse system—a suspension of titanium dioxide of the anatase form. We have noted a strong relationship between the flocculating indicators and the intensity of selective contact between oppositely charged fragments of macromolecules of ionogenic polyacrylamide flocculants and as a result of it, from the mode of introduction into the disperse system of polymer components: simultaneously or sequentially.
