  • Does Pam increase water content in iron tailings?
  • As the molecular weight increased, the effect of PAM increased significantly. When the molecular weight was 300w, the saturated water content of the iron tailings with PAM mass concentrations of 0.01%, 0.04%, 0.08%, and 0.16% increased by 2.22%, 2.89%, 8.79%, and 12.88% compared to CK, respectively.
  • Does Pam increase soil water infiltration?
  • Studies have shown that the application of PAM can increase soil water infiltration 25, 26, but this effect is not absolute. Generally speaking, the higher the molecular weight and mass concentration of PAM, the better the water retention effect. However, if the mass concentration of PAM is too high, it will inhibit the infiltration of soil water.
  • Which anionic Polyacrylamide is used in the experiment?
  • The anionic polyacrylamides (PAM) used in the experiment with molecular weights of 300w, 600w, 800w, and 1000w, which were produced by Henan Zhongbang Environmental Protection Technology Corporation in China, with a degree of hydrolysis of 30% and a particle size of about 80 mesh.
  • Does Pam increase infiltration capacity?
  • With the increase of PAM mass concentration, adding PAM of 1000w molecular weight to iron tailing decreased infiltration capacity, but treatments of other molecular weights all initially increased then decreased infiltration capacity.
