  • What is the molecular weight of Pam?
  • The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water retention characteristics. 6, 7, 8 PAM is widely used in environmental systems including: 1. 2. 3.
  • What is Pam used for in water treatment?
  • PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good settling properties. 38 Cationic, nonionic, and anionic PAM have all been studied for flocculation.
  • Can high molecular weight Pam be used for degradation?
  • This paper provides a short review of current applications of high molecular weight PAM, including the potential for PAM degradation by chemical, mechanical, thermal, photolytic, and biological processes.
  • Does the molecular weight of Pam decrease with time?
  • Characterization of extractable radioactivity by means of GPC-analysis showed a significant decrease of the molecular weight of the PAM with time. The decrease in molecular weight indicates a breakdown of the polymer backbone (the C–C-chain), and is assumed to be primary degradation.
