  • What is polyacrylamide used for?
  • Polyacrylamides, particularly polyelectrolytes, are widely used for water treatment as flocculants/coagulants and in tertiary oil recovery, as well as in various other applications such as sewer grouts.
  • 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.
  • What is the rate of polyacrylamide polymerization?
  • The rate of polyacrylamide polymerization is reported to be very low at temperatures below 45°C according to Lin. The rate of polymerization increases with temperature due to the increasing rate of primary free radicals production that initiates the polyacrylamide polymerization.
  • What are the dosage standards for acrylamide?
  • The dosage standards for acrylamide are indirectly based on the maximum concentration of acrylamide that would result from the use of a commercial formulation, with a maximum acrylamide content of 0.05 % in the formulated polymer.
