  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • Why is anionic polyacrylamide not bioavailable?
  • teria for persistence.Pharmacokinetic studies showed that anionic polyacrylamide was not bioavailable to rats when ingested; this is most likely due to its large size (high molecular weight) and presumed resistance to break down in the astrointestinal tract. Anionic polyacrylamide is thus not expected to be bioavailable to aquatic or
  • How is anionic polyacrylamide synthesized?
  • Synthesis mechanism The anionic polyacrylamide was synthesized by copolymerizing AM and SAS monomers. The essence of copolymerization is the free radical reaction. Thus, this chain reaction can be divided into three distinct processes: initiation, propagation, and termination.
  • What is the atomic percentage of Apam?
  • And the atomic percentage values are listed in Table 3. Meanwhile, the theoretical molecular formation of APAM and APAM-T is (C 3 H 5 ON) 8 (C 3 H 5 SO 3 Na) 2, when the dosage of SAS in the total monomer is 20 %, O/C = 0.467, N/C and S/C = 0.667. It coincided with the result of XPS analysis approximately.
