Abstract The relationship of flocculation by water-soluble polymers to the classical phenomena of colloid chemistry is pointed out and the contributions of electrostatic and non-electrostatic forces are discussed. Modern flocculants have a high degree of polymerization (e.g. c. 50 000) and an extremely extended configuration when dissolved in a favourable solvent; this factor explains qualitatively some of the peculiarities of flocculation by polymers and indicates the need for rational control of their use if optimum results are to be achieved. It is concluded, however, that a quantitative theory of specific flocculant systems is not possible at present. Future developments in flocculation technology will almost certainly include introduction of cheaper or more selective flocculants, improved control through the use of auxiliary reagents and more sophisticated consideration of the surface chemistry of materials that have to be flocculated. 2、Flocculation Mechanism: Charge Neutralization and Bridging Herman E.

Science 28 June 1968: Vol. 160. no. 3835, pp. 1449 - 1450 DOI: 10.1126/science.160.3835.1449 Abstract： Electrophoresis measurements and electron-microscope observations with two model colloids and a polymeric flocculant show zeta-potential changes and details of floc structure. Fibers of the flocculant extend radially from the particle surface and vary in thickness from 20 to 300 angstroms. Both charge neutralization and bridging may function simultaneously. 3、第三篇基本信息On the mechanism of flocculation of suspensions by polyacrylamide 期刊 Journal of Mining Science 出版社 Springer New York ISSN 1062-7391 (Print) 1573-8736 (Online) 期 Volume 3, Number 3 / 1967年5月
