  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
  • 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.
  • What is the molecular weight of acrylamide (Pam)?
  • Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units. The term “PAM” is commonly used to refer to any polymer that contains acrylamide as one of its monomers.
  • Can polyacrylamide contribute to residual polymer formation?
  • Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
