  • Can FTIR spectroscopy detect ketone and aldehyde in mechanically degraded Pam?
  • Fourier transform infrared spectroscopy (FTIR) and Nuclear magnetic resonance (NMR) have been used to identify specific functional groups; ketone, aldehyde, and carboxylic groups have all been reported in chemically, photolytically, and thermally degraded PAM. To the best of our knowledge, mechanically degraded PAM has not been chemically analyzed.
  • Can nonionic polyacrylamide be used as a gel fracturing fluid?
  • Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
  • Does Pam solvated with Fe 3+ release acrylamide?
  • It was found that PAM solvated with Fe 3+ generated ppb levels of acrylamide after exposure to sunlight under acidic conditions (pH 6). They concluded that release of acrylamide would be insignificant at low levels of iron (<0.02 mg/L) under alkaline (7.5–8.5) conditions.
  • Does biological filtration improve polyacrylamide biodegradation?
  • Freedman, D. E. et al. Biologically active filtration for fracturing flowback and produced water treatment. J. Water Process Eng. 18, 29–40 (2017). Dai, X. et al. Waste-activated sludge fermentation for polyacrylamide biodegradation improved by anaerobic hydrolysis and key microorganisms involved in biological polyacrylamide removal.
