  • Are amide-based coagulant polyacrylamide precursors of haloacetamides?
  • Shunke Ding, Wenhai Chu, Tom Bond, Zhongqi Cao, Bin Xu, Naiyun Gao. Contribution of amide-based coagulant polyacrylamide as precursors of haloacetamides and other disinfection by-products.
  • Can amide-based organic polymer coagulants serve as a source of Hacam?
  • Here we report that the amide-based organic polymer coagulants polyacrylamide (PAM) and its monomer acrylamide (AM) can serve as a source of HAcAm and other DBPs including trihalomethanes (THMs) and haloacetonitriles (HANs) during chlor (am)ination.
  • Do amide-based organic polymer coagulants affect water quality?
  • Conclusions This study is to report that amide-based organic polymer coagulants and their monomers (i.e. PAM and AM) can adversely affect water quality, beyond the direct exposure to AM and PAM dissolved in water, because of their ability to produce toxic DBPs during disinfection.
  • Is dcacam undetectable in polyacrylamide?
  • ... amide-based coagulants (Ding et al., 2018; Wang et al., 2018); polyacrylamide samples yielded 0.040% M/M of DCAcAm in chlorination and undetectable in chloramination, against 0.034% M/M and undetectable, respectively, in the current study.
