摘要：

The flocculation of cane sugar muds with commercial acrylamide-sodium acrylate copolymers has been investigated through the measurement of setting rates and residual turbidities. The flocculation efficiencies of the copolymers were observed to depend on their composition, microstructure, and molecular weight, and the zeta potential of the mud particles. Adsorption of polymer at the surface of the particles was shown to occur through interaction with the acrylate groups. The experimental results are consistent with a bridging mechanism for the flocculation process, in which an observed optimum copolymer composition is associated with polymer adsorption which is sufficiently strong to resist mild shear forces yet allows the extension of polymer "loops" and "tails" into solution.
