In one soils maximum response was obtained at 125 kg ha -1 for the polyacrylamide with no additional response from the polysaccharide. At a lower rate the two polymers gave additive response. In the second soil, which was less responsive, especially to the polysaccharide, the combined effects were close to additive.

Abstract 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 ...

Is polyacrylamide a good soil conditioner?

However, as these solutions are proposed, numerous doubts and opposing opinions are emerging. Polyacrylamide (PAM), also known as “soil conditioner”, “soil amendment” and “soil stabilizer” in soil science (Gilda Dell'Ambrogio and Wong, 2019), is commonly used to modify the unfavorable and damaged characteristics of soil.

How does polyacrylamide stabilize soil?

The addition of polymer to the soil stabilizes existing aggregates and strengthens the mutual binding of adjacent particles. The stabilizing efficiency of polyacrylamide is mainly determined by the adsorption of its macromolecules on the surface of soil particles .

Does polyacrylamide contribute to flocculation process?

The presence of polyacrylamide with high molecular weight contributes to flocculation process. However, the structure of flocs depends on clay mineral type. These micro-aggregates of soil particles with poly-electrolyte can be formed in both neutral and acidic solutions.

What are the different types of polyacrylamide?

Polyacrylamides can be classified into nonionic, anionic, and cationic ones [4, 5]. Each of these types due to their proper-ties is used in many industries, mainly in water treatment, mineral processing, or soil conditioning . Application areas of abovementioned polyacrylamide types depend on the specific function of the polymer needed.

What causes nonionic polyacrylamide adsorption?

Nonionic polyacrylamide adsorption on clay minerals is mainly caused by van der Waals forces , whereas cationic or anionic forms adsorb and bind soil particles through electrostatic forces or bridge formation between PAM charged moieties and solid surface group [1, 80].

What is the stabilizing efficiency of polyacrylamide?

The stabilizing efficiency of polyacrylamide is mainly determined by the adsorption of its macromolecules on the surface of soil particles . The aggregate formation contributes to several beneficial phenomena such as stability increase, reinforcement of soil structure, water infiltration promotion as well as erosion limitation .
