Transfer and degradation of polyacrylamide-based flocculants in hydrosystems: a review | Environmental Science and Pollution Research - Springer

The aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (PAM)-based flocculants in hydrosystems. Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain

Anionic polyacrylamide efficiency in goethite removal from aqueous solutions: goethite suspension destabilization by PAM - International Journal

11 Citations Explore all metrics Abstract The main aim of the study was to investigate the anionic polyacrylamide (PAM) efficiency as a flocculant relative to goethite particles. This mineral is a toxic waste produced during hydrometallurgical processes and, as a result, poses a threat to the environment.

Anionic polyacrylamide influence on the lead(II) ion accumulation in soil ¨C the study on montmorillonite | Journal of Environmental Health

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.

Effect of polyacrylamide on rheology of fresh cement pastes

Abstract. In this paper, we study the effects of polyacrylamide (PAM) on both aqueous solutions and fresh cement pastes. Our solution viscosity and hydrodynamic radii measurements in various solutions suggest that calcium ions lead to a cross-linking of anionic PAM and to the formation of PAM micro-gels.
