Heterocoagulation. Part 3.—Interactions of polyvinyl chloride latex with Ludox Hs silica

摘要: The stability of a mixed colloidal dispersion consisting monodispersed PVC latex and Ludox HS silica particles in the presence counterions 1+, 2+ 3+ charge has been studied by light scattering, electrokinetic adsorption techniques. It was found that either (1), selective coagulation or (2), stabilization against electrolytic coagulation, can occur depending upon experimental conditions. deposition onto follows Freundlich-type isotherm. theory heterocoagulation is used to explain various phenomena observed.
