  • 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.
  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
  • Should polyacrylamides be used in drinking water?
  • For health concerns, the use of polyacrylamides in drinking water has been subjected to closer evaluation during the last decade. Currently, dosage standards are indirectly based on the maximum concentration of acrylamide that would result from using a commercial formulation of known acrylamide content.
  • How to make polyacrylamide solution?
  • In a 50-ml glass bottle, mix acrylamide, H 2 O, TEMED, and 10% APS according to the recipe in Table 1 . Table 1. CAUTION: The linear polyacrylamide solution can be made as inert or activated with the capability of binding adhesive proteins.
