The objective of the present study is to improve the behavior of sulfonated polyacrylamide (SPA) by adding Laponite and/or chromium(III) with a focus on enhanced oil recovery applications. The resultant systems are weak nanocomposite hydrogels which are subjected to rheological, thermal stability and adsorption tests. The interactions between ingredients of the hydrogel are investigated by
Study of adsorptive behavior of sulfonated polyacrylamide
The adsorption of sulfonated polyacrylamide (SPAM) as an enhanced oil recovery polymer onto carbonate rock particles was studied using UV-visible spectroscopy. The effect of the experimental parameters of polymer concentration, salinity and temperature was investigated. The results showed that polymer adsorption increased as the SPAM concentration increased, but decreased as temperature and

Adsorptive potential of sulfonated poly
Research highlights Chemical modification of cellulosic materials, followed by functionalization, is a promising technique to improve the adsorption potential as well as to prevent the solubility in acidic and basic medium. A novel sorbent, Poly(glycidylmethacrylate)-grafted cellulose having sulfonate functional group (PGMA-g-Cell-SO 3 H) was synthesized by graft copolymerization of
physico-chemistry characterization of sulfonated polyacrylamide polymers, and states the objectives of this research. It starts with a general overview about polymer applications in oil industry, and followed by the viscosity and adsorption/retention study of polymers which must be well known before the application processes.

- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- Can anionic polyacrylamide (PAM) be used to treat animal waste?
- The application of anionic polyacrylamide (PAM) to soils and/or vegetative treatments may also provide a cost-effective way to dramatically reduce bacteria and nutrient loads in animal waste effluent and thereby reduce pollution in surface and ground waters receiving these effluents.
- What is water soluble anionic polyacrylamide (PAM)?
- Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1–10 g m −3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.
