  • What are cationic polyacrylamide copolymers?
  • Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
  • Are cationic polyacrylamide copolymers bad for the environment?
  • Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
  • Which cationic polyacrylamide is synthesized through UV initiation?
  • Recently, Ma et al. used acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride (DMC) to synthesize a novel cationic polyacrylamide (CPAM) through low-pressure ultraviolet (UV) initiation.
  • Do cationic polyacrylamide copolymers degrade in soil after land-spreading?
  • This project demonstrated that the synthetic cationic polyacrylamide copolymers (PAMs) incorporating C–C-bonds in the main chain slowly degrade in soil after land-spreading as a component of MWWTP sludge.
