Get Price- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- Which cationic polyacrylamide is synthesized through UV initiation?
- Recently, Ma et al. used acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride (DMC) to synthesize a novel cationic polyacrylamide (CPAM) through low-pressure ultraviolet (UV) initiation.
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
- Can cationic flocculants be synthesised by UV-induced polymerization?
- 4. Conclusions This study demonstrated facile synthesis of two cationic flocculants via UV-induced polymerization of monomers [2- (acryloyloxy)ethyl]trimethylammonium chloride and (3-acrylamidopropyl)trimethylammonium chloride for harvesting freshwater green microalgae ( C. vulgaris) and marine red microalgae ( P. purpureum ).
