  • What is ionic polyacrylamide?
  • The ionic forms of polyacrylamide has found an important role in the potable water treatment industry. Trivalent metal salts, like ferric chloride and aluminum chloride, are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate.
  • What is the standard state of polyacrylamide?
  • Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
  • ) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -).
  • Is polyacrylamide contaminated with acrylamide?
  • Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
  • How to make polyacrylamide solution?
  • Solution should be made up at 0.1-0.3% solid. Make-up water temerature should be between 10 o C to 40 o C for optimum product performance. Following dispersion into agitated water, stirring should be continue for about an hour. The liquid polyacrylamide are stable for one week. 5. Company Exhibition
