  • 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.
  • How much Acrylamide is in groundwater?
  • In a monitoring study on the water circuit of the quarry, acrylamide levels were between 1.01 and 5.66 μg/L in treated water and between 0.08 and 0.41 μg/L in supernatant water, and contamination with 0.01–0.02 μg/L was also measured in groundwater .
  • What is a polyacrylamide soluble polymer?
  • Polyacrylamide: This is a water-soluble polymer formed from acrylamide (a compound with a molecular formula C 3 H 5 NO) subunits. PAMs is most often used to increase the viscosity of water (creating a thicker solution) or to encourage the flocculation of particles present in water.
  • Can cationic polyacrylamides be used in water treatment?
  • This applies to both the anionic and non-ionic polyacrylamides, but residual levels from cationic polyacrylamides may be higher. Acrylamide was detected at levels of <5 μg/l in both river water and tap water in an area where polyacrylamides were used in the treatment of potable water.
