  • Do polyacrylamides bond with smectite?
  • The objective of this study was to investigate the probable bonding mechanisms between PAM and smectite, a common clay mineral that occurs in soils and sediments. Three polyacrylamides – nonionic PAM 903N, cationic PAM 494C, and anionic PAM 836A – were investigated.
  • Are nonionic acrylamide units bonded to smectite?
  • The similar IR-band shifts of the nonionic units in both the cationic-copolymer PAM 494C and the anionic-copolymer PAM 836A as those of the nonionic PAM 903N suggest that the nonionic acrylamide units in the copolymers were bonded to smectite by similar mechanisms as those in the PAM 903N. 4. Discussion
  • Can Pam be reversibly adsorbed on soil & smectite?
  • It has been shown that PAM can be irreversibly adsorbed on soils , and clay minerals ; however, the mechanisms of bonding are still not clear. Here we focus on the bonding modes between PAM and smectite. Smectite is a common clay mineral that occurs in soils and sediments.
  • What is water soluble polyacrylamide (PAM)?
  • Water-soluble polyacrylamide (PAM) has a variety of applications, such as soil erosion control, water treatment, soil conditioning, and oil recovery. In these applications, the polymer reacts mainly with clay minerals that occur in soils, sediments, or as suspended particles.
