Polyelectrolyte - Wikipedia

Tools Chemical structures of two synthetic polyelectrolytes, as examples. To the left is poly (sodium styrene sulfonate) (PSS), and to the right is polyacrylic acid (PAA). Both are negatively charged polyelectrolytes when dissociated. PSS is a 'strong' polyelectrolyte (fully charged in solution), whereas PAA is 'weak' (partially charged).

A survey on cationic polyelectrolytes and their applications

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

Generally, cationic flocculants have been found to be most toxic to fish but this varies for crustaceans. Flocculants appear to act mainly by acute toxicity, probably by physical blocking and mucous production of gill tissue and sorption to small invertebrates (Biesinger et al. 1976, Cary et al. 1987, Beim & Beim 1994).

Cationic Powders are used for charging polymers after dissociation in aqueous solution. They are known to have ion exchanging, conditioning, emulsifying, and dispersing ability depending upon purpose of their use. They play an important role in treatment of waste water by flocculating or precipitating suspended solids for their efficient removal.

Cationic Polyelectrolyte - Chemtex Speciality Limited

Cationic Polyelectrolytes are used for emulsion breaking, promoting filtration and sludge dewatering. The primary use is waste water treatment. As a primary organic coagulant, it neutralizes negatively charged colloidal particles and thus induces flocculation and sedimentation which reduces sludge volume.
