Abstract:
Fresh suspensions of the thermal silica, Aerosil, are flocculated by polyacrylamide. Infra-red spectroscopy and use of simple hydrogen-bonding compounds as competitors suggest that the polymer is adsorbed on incompletely hydrated sites, perhaps by hydrogen-bonding on to the so-called "free" silanol groups on the surface of silica. In this system, adsorption and flocculation are non-ionic in character, the silica particles being joined by polymer molecules that are anchored to two particles.
