  • Can hydroxyl radicals cause acrylamide monomer release?
  • Chain scission of PAM by hydroxyl radicals could lead to the release of acrylamide monomer. Woodrow et al.85 detected 3.5 ppb acrylamide (0.038% of the monomer units in the initial polymer) after 3 h exposure to simulated sunlight in the presence of 4.5 mg/L ferric ion.
  • What is a polyacrylamide & oligomer?
  • Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.
  • Does anionic polyacrylamide improve coagulation-flocculation process?
  • Aguilar, M. I. et al. Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid. Chemosphere 58, 47–56 (2005). Muller, G., Fenyo, J. C. & Selegny, E. High molecular weight hydrolyzed polyacrylamides.
  • How dangerous is polyacrylamide (PAM)?
  • 4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.
