Interactive effects of clay and polyacrylamide properties

Turbidity reduction is essential for improving surface water quality. Eroded fine sediments not only increase surface water turbidity, they also carry pollutants such as heavy metals and pathogens. The objectives of this study were to investigate the mechanisms of adsorption and desorption of polyacrylamide (PAM) by pure kaolinite and montmorillonite, and to test the ability of PAM to ...

Interaction effects of polyacrylamide application

Polyacrylamide (PAM) is often applied to control soil erosion from water but its effectiveness on different nutrients is not clear. This study tested the influence of PAM application rate, PAM molecular weight, and soil slope gradient on K+ and N losses as well as their interactive effects under simulated rainfall in the laboratory.

Polyacrylamide−Clay Nanocomposite Hydrogels: Rheological

The free-radical polymerization of acrylamide in aqueous clay dispersions and the structure of the resulting polymer−clay nanocomposite hydrogels have been investigated by rheometry using oscillatory deformation tests. Laponite was used as clay particles in the hydrogel preparation. The reactions were carried out with and without the presence of the chemical cross-linker N,N‘-methylenebis ...
