optimizing the flocculation effect of cationic polyacrylamide
cationic polyacrylamide (cpam) is a commonly used flocculant for water treatment. factors that affect the flocculation effect and can be controlled manually include the type and dosage of cpam, wastewater ph, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of cpam. in this paper, the optimal flocculation conditions of a novel cpam were

research on a new cationic polyacrylamide (cpam) with high purity
flocculation is a common method to improve filtration efficiency and purify water quality in water supply plants where the commonly used flocculant is cationic polyacrylamide (cpam) (vandamme et al. 2010; teh et al. 2016). for sludge dewatering, cpam shows superior conditioning performance and obtained more and more attention.

study on flocculation performance and mechanism of cationic
it has been proven that cationic polyacrylamide (cpam) exhibits better flocculation performance on clay minerals due to its high positive charge density and water solubility over the past few decades [14],,. quaternary ammonium salts are the most commonly used positive groups of cpam, including dmc, 2-methylacryloxyethyl trimethyl

characteristics and applications of nonionic polyacrylamide
the characteristics of nonionic polyacrylamide pam can be simply divided into the following three points: it has relatively good water solubility and can be completely dissolved even in cold water. a small amount of nonionic polyacrylamide can exert a significant flocculation effect. it is beneficial for saving dosage.

- What is cationic polymerization?
- Cationic polymerization is used in the production of polyisobutylene (used in inner tubes) and poly ( N-vinylcarbazole) (PVK). Monomer scope for cationic polymerization is limited to two main types: alkene and heterocyclic monomers. Cationic polymerization of both types of monomers occurs only if the overall reaction is thermally favorable.
- Why do cationic polymers form stable cations?
- In the case of alkenes, this is due to isomerization of the monomer double bond; for heterocycles, this is due to release of monomer ring strain and, in some cases, isomerization of repeating units. Monomers for cationic polymerization are nucleophilic and form a stable cation upon polymerization.
- What is cationic polymerization of olefin monomers?
- Cationic polymerization of olefin monomers occurs with olefins that contain electron-donating substituents. These electron-donating groups make the olefin nucleophilic enough to attack electrophilic initiators or growing polymer chains.
- What is initiation in cationic polymerization?
- Initiation is the first step in cationic polymerization. During initiation, a carbenium ion is generated from which the polymer chain is made. The counterion should be non-nucleophilic, otherwise the reaction is terminated instantaneously.
