  • Does anionic Pam improve soil water infiltration?
  • Anionic PAM can regulate soil water infiltration, enhance soil water retention capacity, and inhibit soil water evaporation. Flanagan et al. 10 added a small amount of anionic PAM to tap water under artificial rainfall, and the results showed that the addition of PAM greatly increased iron tailings water infiltration.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • Does Pam molecular weight affect water holding capacity of iron tailings?
  • Therefore, the maximum PAM mass concentration of 0.16% in the experimental design was selected to observe the effect of PAM molecular weight on the water holding capacity of iron tailings.
  • How do high molecular weight PAMS work as flocculants?
  • High molecular weight PAMs (10 6 to 10 7 g mol −1) work as flocculants by causing suspended particles to bind together to form larger aggregates, which can settle out quickly from solution leaving a clear supernatant (Heath et al. 2006).
