摘要
Using a single-particle light-scattering technique, we investigated rapid coagulation with monodisperse Fe2O3 particles (haematite). It was revealed that the value of the velocity constant of coagulation, k(11) = 11.0 x 10(-12) cm(3) s(-1), was significantly closer to predictions by Smoluchowski's theory than to theories which allow for hydrodynamic and van der Waals interactions between spherical particles.
