  • What is a polyacrylamide & oligomer?
  • Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.
  • 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 a water soluble polyelectrolyte?
  • Part of the book series: Springer Proceedings in Physics ( (volume 246)) Polyacrylamide is a water-soluble synthetic polyelectrolyte which consists of repeating units (forming a chain structure and containing hydrophilic groups).
