  • Does polyacrylamide-cellulose blend improve water retention?
  • Among prepared composites and blend polymers, the polyacrylamide-cellulose blend showed positive results concerning water retention and improving soil proprieties.
  • Is polyacrylic acid a good water retention agent?
  • On the other hand, although water-retention agents based on synthetic polymers, such as polyacrylicacid and polyacrylamide, show the advantages of low cost, long service life and high water absorption rate, their degradation products may have an adverse effect on the environment and plant growth.
  • 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.
  • How to clean polyacrylamide?
  • The obtained polyacrylamide was cleaned by dissolved it in bidistilled water then precipitated second time in methanol to eliminate all initiator and monomer traces, then filtered at Buchner, desiccated using inert nitrogen atmosphere (anhydride N 2) under vacuum at 30°C
