  • What are acrylamide and polyacrylamide used for?
  • Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 °C for elongated time.
  • Is acrylamide biodegradable?
  • Acrylamide is subject to biodegradation in both soil and surface water. Acrylamide in environmental water had to be removed by conventional water treatment processes; however, treatment with ozone or potassium permanganate may decrease acrylamide concentration.
  • 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.
  • How does acrylamide release affect environmental water?
  • Acrylamide release from PAM in different ways may cause the contamination of the environmental water. Especially, undeveloped countries that consume treated water as livestock and household use may be affected by acrylamide contamination by degradation of PAM in environmental water sources.
