  • What is anionic polyacrylamide (PAM)?
  • Volume 224, article number 1382, ( 2013 ) Anionic polyacrylamide (PAM) is a linear, water-soluble anionic polymer that is widely used for erosion control and water quality protection.
  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 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.
  • 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.
  • What is the mass concentration of Pam?
  • PAM had 4 molecular weights of 300w, 600w, 800w, and 1000w, and 5 mass concentrations of 0% (CK), 0.01%, 0.04%, 0.08%, and 0.16%, for a total of 17 treatments with each treatment in replicates of 3, for a total of 51 groups. The saturated hydraulic conductivity was measured using the permeation bucket method.
