The use of photon correlation spectroscopy for estimating the rate constant for doublet formation in an aggregating colloidal dispersion

Stability in Colloidal Mixtures Containing Particles with a Large Disparity in Size

“…In order to study the aggregation kinetics in colloidal dispersions, a number of experimental techniques have been developed (2). Light-scattering techniques (including turbidity (2-4), scattered light intensity (5-7, 40, 41), and autocorrelation of the scattered light (42)(43)(44)(45)(46)) are the most commonly employed.…”

Role of Polymer Flexibility in the Stabilization of Colloidal Particles by Model Anionic Polyelectrolytes

“…DNA was added (from 5 to 100 ml in volume) and the electrolyte concentration adjusted by adding 1 mL of concentrated NaCl solution. The change in the average radius of particle aggregates with time (dr/dt) was measured and related to the experimental coagulation rate constant (k exp ) using an expression reported by Virden and Berg (25), namely, …”

Influence of pH and Humic Acid on Coagulation Kinetics of Kaolinite: A Dynamic Light Scattering Study

“…single particle detection methods (12)(13)(14), low-angle static light scattering (15), turbidimetry (16), and dynamic light The dispersion-coagulation behavior of clay suspensions scattering (17,18). However, most of these techniques have is not only of great importance in soil and environmental not yet been applied to clay mineral or soil clay suspensions, sciences, but it also plays a key role in the ceramics, petro-which are usually rather polydisperse.…”
