  • What is Pam polymer?
  • PAM is one of the most widely used water-soluble polymer species with a large number of pendant amide groups presenting on its molecular backbone. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds.
  • Does Pam solvated with Fe 3+ release acrylamide?
  • It was found that PAM solvated with Fe 3+ generated ppb levels of acrylamide after exposure to sunlight under acidic conditions (pH 6). They concluded that release of acrylamide would be insignificant at low levels of iron (<0.02 mg/L) under alkaline (7.5–8.5) conditions.
  • Is acrylamide monomer a carcinogen?
  • Although the PAM used in environmental systems has a very high MW, it is well known that PAM can undergo degradation by a variety of mechanisms, significantly increasing its mobility and potentially leading to the release of acrylamide monomer, a known toxin and potential carcinogen.
  • Is Pam a porous molecule?
  • PAM is highly retained in porous media, such as soil, and it easily settles in waterbeds. 100, 145 PAM is also too large to penetrate biological cell membranes. 146 However, smaller PAM with different functional groups could behave very differently.
