  • What is nonionic polyacrylamide?
  • Nonionic polyacrylamide is a high polymer with a high molecular weight and a low ion exponent, which has the function of flocculation, dispersal, thickening, bonding, film-forming, relating, and colloidal stability. Its flocculation is hardly influenced by the PH value and the salt, and in the process of acid wastewater
  • What is anionic polyacrylamide?
  • Anionic polyacrylamide is polymer with a large number of negatively charged moieties in the long chains of the PAM macromolecules. It can be obtained by partial hydrolysis of polyacrylamide neutral amide groups, which is shown in (3). This process occurs under moderate temperature by adding sodium hydroxide to the PAM solution [4, 6].
  • What causes nonionic polyacrylamide adsorption?
  • Nonionic polyacrylamide adsorption on clay minerals is mainly caused by van der Waals forces , whereas cationic or anionic forms adsorb and bind soil particles through electrostatic forces or bridge formation between PAM charged moieties and solid surface group [1, 80].
  • Is polyacrylamide ionic or cationic?
  • Polyacrylamide is a water-soluble synthetic polyelectrolyte which consists of repeating units (forming a chain structure and containing hydrophilic groups). Due to the different nature of the groups present in the macromolecules, polyacrylamides can be divided into nonionic, anionic, and cationic ones.
