  • Does anionic polyacrylamide influence lead ion accumulation in soil?
  • Fijałkowska, G., Szewczuk-Karpisz, K. & Wiśniewska, M. Anionic polyacrylamide influence on the lead (II) ion accumulation in soil – the study on montmorillonite.
  • Can anionic polyacrylamide be used to remediate soil contaminated with heavy metals?
  • Anionic polyacrylamide makes the Pb (II) accumulation on the montmorillonite surface larger and, as a consequence, reduces the Pb (II) availability to organisms. Therefore, this macromolecular compound can certainly be used to remediate soils contaminated with heavy metals.
  • Does anionic polyacrylamide affect lead ion sorption on montmorillonite surface?
  • The main aim of this study was investigation of anionic polyacrylamide (AN PAM) effect on the lead (II) ion sorption on the montmorillonite surface. The effects of Pb (II) ion concentration, sequence of heavy metal and anionic polymer addition into the system as well as anionic group content in the PAM macromolecules were also studied.
  • Does an anionic polyacrylamide increase adsorption?
  • Anionic polyacrylamide increased this value significantly (it was 0.11 mg/m 2 with AN PAM 5% and 0.11 mg/m 2 with AN PAM 30%). The lead (II) ions presence causes a slight increase of the anionic PAM adsorption on the montmorillonite surface.
