  • Is polyacrylamide a cationic or nonionic polymer?
  • Recently, polyacrylamide was introduced in geotechnical engineering into the process of clay treatment . Regarding the type of polymer charge, polyacrylamide can be divided into three types: nonionic (PAM), anionic (APAM), and cationic (CPAM).
  • 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].
  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
  • 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].
