  • What is the flocculation mechanism of polyacrylamide?
  • Schematic presentation of flocculation mechanism of polyacrylamide: a weak charge adsorption of randomly distributed cationic units, b strong charge adsorption of cationic microblock structure and c inter-molecular hydrophobic association of hydrophobic units
  • 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 ).
  • Is grafted flocculant effective compared to commercial cationic polyacrylamide?
  • The grafted flocculant was found to be effective compared to commercial cationic polyacrylamide.
  • Is polyacrylamide hydrophobically associating with cationic microblock structure labelled TP-ADL?
  • In this study, a hydrophobically associating polyacrylamide with cationic microblock structure labelled as TP-ADL was synthesized through UV-initiating template copolymerization using cationic methacryloxyethyltrimethyl ammonium chloride (DMC), hydrophobic lauryl acrylate (LA) and acrylamide (AM) as monomers.
