Impact of anionic polyacrylamide on stability and surface properties of the Al2O3–polymer solution system at different temperatures By Małgorzata Wiśniewska, Stanisław Chibowski, Teresa Urban, Dariusz Sternik and Konrad Terpiłowski
The main purpose of the study was to examine lead(II) ion immobilization on the kaolinite surface and determine the effect of soil flocculant (macromolecular compound) on this process. For this reason, the adsorption measurements of anionic polyacrylamide and/or Pb(II) ions on the kaolinite surface were performed. Moreover, the impact of heavy metal on electrokinetic and stability properties

Polyacrylamide degradation and its implications
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21
An anionic polyacrylamide – AN PAM (Korona) with a high-molecular weight and various ionic contents was applied in experiments as an adsorbate.The full description of applied polymeric samples is presented in Table 2.The dissociation degree of carboxyl groups in the PAM macromolecules was determined by means of the potentiometric titration method (Wiśniewska et al., 2015b, Wiśniewska et al
Impact of polyacrylamide with different contents
PAM adsorption on Cr 2 O 3 surface increases with rise of carboxyl groups content.. Decrease of PAM adsorption with pH rise was obtained. • PAM addition influences the surface properties of Cr 2 O 3 suspension.. At pH 3 and 9 stability deterioration of Cr 2 O 3 particles covered with PAM occurs.. Suspension stability is affected by specific conformation of adsorbed PAM chains.
Anionic Polyacrylamide Guidance July 2002 4 (2) Site-Specific Testing and Instructions Users must obtain site-specific soil and water testing and guidance from a qualified manufacturer to ensure that an (a) Anionic PAM product, (b) additives, and (c) application scheme are selected that is tailored to site-specific soil
The tip of the iceberg: Three case studies of spill risk
1. Introduction. Spill research is a fairly young discipline, often produced in highly episodic ways in reaction to spills that occurred near major population centers or otherwise received substantial media attention (Murphy et al., 2016).Most modeling studies in oil spill research are concerned with the fate and effects of oil after it has been spilled and subsequently moves through the
