Polyelectrolyte - Wikipedia
网页Polycations and polyanions are polyelectrolytes. These groups dissociate in aqueous solutions (water), making the polymers charged. Polyelectrolyte properties are thus similar to both electrolytes (salts) and polymers (high molecular weight compounds) and are sometimes called polysalts.

Ecotoxicological assessment of a polyelectrolyte flocculant
网页2011年12月1日 · The present study found that the toxicity of a polyelectrolyte flocculant to freshwater biota varied considerably between species. It is also clear from the results that the active ingredient, PAM, is the primary toxicant to most species.
Polyelectrolyte flocculants in harvesting microalgal biomass …
网页2017年6月1日 · This review focusses on polyelectrolyte flocculants to harvest cultivated microalgae for non-toxic residue free applications of the harvested biomass in the food and the feed industry and evaluates various commercial polyelectrolyte flocculants, their properties and application in harvesting microalgal biomass from high density cultures.
Role of Polyelectrolytes in the Treatment of Water and Wastewater
网页2020年5月31日 · The selection of type of polyelectrolyte for use as coagulant and flocculant aid is generally an important task. Due to the great variation different raw water types and difference in experimental protocols, it is very challenging to predict the type of polyelectrolyte to be used in a particular kind of water.
Polyelectrolyte polymers—Types, forms, and function
网页2022年1月1日 · The high-molecular-weight polymers are generally used as flocculants while low-molecular-weight materials can be used as coagulants, dispersants, scale inhibitors, and fixatives in various applications. Again, the addition of cross-linking monomers can be used to impart branching and structure to the resulting polymers.
Ultra-High-Molecular-Weight, Narrow-Polydispersity …
网页2023年12月7日 · Ultra-high-molecular-weight, water-soluble polyelectrolytes are commonly employed as flocculants for solid–liquid separation via colloidal destabilization, enabling the rapid and efficient removal of particulate matter from wastewater streams.
Polyelectrolyte Complexes in Flocculation Applications
网页2013年1月1日 · This review concentrates on the interactions between oppositely charged polyelectrolytes and on the formation of complexes, which can be used for different applications such as paper retention or water treatment. Three different possibilities for the appearance of polyelectrolyte complexes (PECs) in flocculation applications are described.
