Effect of cationic polyacrylamide adsorption kinetics
The effect of polymer adsorption kinetics and ionic strength on the dynamics of particle flocculation was quantified using a model system consisting of precipitated calcium carbonate (PCC) and cationic polyacrylamide (CPAM) at a low shear rate. All early flocculations detectable by a photodispersion analyzer (PDA) happened in nonequilibrium
We quantified the adsorption kinetics of cationic polyacrylamides (CPAMs) from suspension onto precipitated calcium carbonate particles (PCCs) and its effect on the PCC flocculation dynamics. The effects of polyelectrolyte charge density and suspension ionic strength were investigated using PCC as model of polydispersed colloid.

The adsorption of modified polyacrylamides (PAM) at the silica surface has been studied by ellipsometry. To study the influence of the type of modification of the polyacrylamide on the adsorption behaviour, we have used cationic, anionic and hydrophobically modified polyacrylamides with varying charge density and degree of hydrophobisation.
Kinetics of Adsorption of Anionic, Cationic, and Nonionic
The kinetics of adsorption of anionic, nonionic, and cationic surfactants on a cellulose−water interface were investigated. The effects of monovalent, divalent, and a mixture of mono- and divalent salts on the adsorption kinetics of anionic surfactant were also investigated. The cellulose surface is shown to have dual sites of hydrophobic and hydrophilic nature.
The adsorption kinetics were determined with 400 mg/L Pb 2+ and Cd 2+ solutions by varying the adsorption time from 5 to 120 min, and the pseudo-first-order equation and pseudo-second-order equation were carried out to describe the adsorption process. All adsorption experiments were repeated thrice to guarantee the accuracy of the obtained data.

The purpose of the present work was for identify limits for the formation of stable polyelectrolyte multilayers (PEMs) from cationic and anionic starches (with degrees of substitution of 0.04–0.09) on SiO2 surfaces, taking account of the effect of the charge density of the starches and the salt concentration in the surrounding water phase. The experiments were performed at a pH of 6.3 using
Polyelectrolyte multilayers of cationic and anionic starch
adding cationic and anionic polyelectrolytes to the charged surface of wood fibres and fines, to form layers of these polyelectrolytes on the fibres/fines) has in recent years been found to offer great potential both to introduce new properties and to improve the mechanical properties of papers made of the treated fibres.
Surfactant-modified clay minerals are known for their good sorption properties of both organic and inorganic compounds from aqueous solutions. However, the current knowledge regarding the effect of both cationic and nonionic surfactants on the properties of bentonite is still insufficient. Bentonite, with montmorillonite as the base clay, was modified with hexadecethyltrimethylammonium bromide

- What is polyacrylamide (PAM)?
- Polyacrylamide (PAM) is a polymer with a linear-chain structure. This polymer is synthesized by a chemical reaction between acrylamide and acrylic acid. It is water-soluble in nature which drives its applications in multiple industries. PAM comes in powder, liquid, and emulsion form and is a valuable agent in various applications.
