A kinetic investigation of cationic starch adsorption and flocculation in kaolin suspension
TLDR
In this article, the adsorption of cationic starch on the kaolin surface followed Langmuir isotherm (R2 < 0.98) and showed that increase in flocculant dosage resulted in higher rate constants for the flocculation process and lower rate constant for the aggregate breakage.About:

Adsorption and flocculation by polymers and polymer mixtures
John Gregory,Sandor Barany +1 more
TL;DR: The sequence of addition of the polymers is important and the pre-adsorbed polymer can have two important effects: providing adsorption sites for the second polymer or causing a more extended adsorbed conformation as a result of 'site blocking'.

Synthesis, characterization and application of a novel starch-based flocculant with high flocculation and dewatering properties.
TL;DR: A water soluble copolymer flocculant, STC-g-PDMC (starch-graft-poly) was synthesized through grafting a monomer, (2-methacryloyloxyethyl) trimethyl ammonium chloride (DMC), onto starch initiated by potassium persulphate, which diminished the toxicity during the synthesis process.

Cationization of polysaccharides: A path to greener derivatives with many industrial applications
TL;DR: In this article, the main focus is on the substitution with dialkylamino hydroxypropyl and trialkylammonium hydroxy propyl ethers, being that the most common modifications involve the introduction of the 2-hydroxy-3-(trimethylammium)propyl group by reaction of the polysaccharide with 2,3-epoxypropyl trimethyammonium chloride in an alkaline solution, and an alternative to this method involves generation of the reagent in situ from 3-chloro-2-hydrox

Kinetics of a reactive dye adsorption onto dolomitic sorbents.
TL;DR: Experimental studies indicate that charred dolomite has the potential to act as an adsorbent for the removal of Brilliant Red reactive dye from aqueous solution, with the removal rate heavily dependent on both external mass transfer and intra-particle diffusion.

Cationic starch: an effective flocculating agent
TL;DR: In this article, a series of cationic starches (Cat St) were developed by incorporating N-(3-Chloro-2-hydroxypropyl) trimethyl ammonium chloride (CHPTAC) onto the backbone of starch in presence of NaOH.

Temperature influence of nonionic polyethylene oxide and anionic polyacrylamide on flocculation and dewatering behavior of kaolinite dispersions.
TL;DR: The results demonstrate that a temperature-induced conformation change, together with polymer structure type, plays an important role in flocculation and dewatering behavior of kaolinite dispersions.

Adsorption and flocculation behavior of cationic polyacrylamide and colloidal silica
Daniel Solberg,Lars Wågberg +1 more
TL;DR: In this paper, the adsorption of cationic polyacrylamide and silica nanoparticle systems onto a model surface has been compared with the adaption and flocculation of a fiber suspension.

Starch derivatives of high degree of functionalization: 10. flocculation of kaolin dispersions
TL;DR: In this article, the authors investigated the role of ionic strength in the dispersion of cationic potato starch derivatives with a degree of substitution (DS) up to 1.54 and found that flocculation has occurred long before the surface charge neutralization was reached.
