Is polyacrylamide a water soluble polymer?

Polyacrylamide is a synthetic water-soluble polymer with different molecular weight (MW), formed from acrylamide subunits ( Moran, 2007 ). Polyacrylamides have the general chemical formula (−CH2CHCONH2−)n. They can be synthesized commercially in linear or cross-linked structure with MWs ranging from thousands to millions of Daltons.

Does Pam reduce hydraulic conductivity in sand?

They concluded that PAM reduced saturated hydraulic conductivity (40–98 %) in sand but the reductions were less in loamy sand (0–56 %). A study by Malik and Letey (1992) investigated the effect of adding PAM solutions of various concentrations (25−400 mg/L) on the hydraulic conductivity of fine and coarse sands.

Does low molecular weight Pam improve physical properties of sandy loam soil?

The models showed excellent fit to the experimental data, thus supporting our hypothesis. The results suggest that low molecular weight PAM is more efficient in improving the physical properties of sandy loam soil. The modelling approach presented in this work may be extended to other types of soil.

Can polymers improve soil quality?

For more than 40 years organic polymers such as polyvinyl alcohols (PVAs) and polyacrylamides (PAMs) have been used as soil amendment to improve soil quality including soil physical and chemical properties ( Abu-Hamdeh et al., 2018 ).

What is the chemical formula for polyacrylamide?

Polyacrylamides have the general chemical formula (−CH2CHCONH2−)n. They can be synthesized commercially in linear or cross-linked structure with MWs ranging from thousands to millions of Daltons. It is used in numerous applications such as food industry, well drilling, and wastewater treatment as a flocculation agent.

Does sand-polymer adsorption increase hydraulic conductivity?

Bhardwaj et al. (2007) concluded that the hydraulic conductivity of sand-polymer mixture would increase only in case of existing hydraulic head that exert pressure to partially drain the swollen polymer and thus increase the degree of polymer adsorption.
