Evaluation of polyacrylamide-grafted-polyethylene glycol
The polyacrylamide-grafted-polyethylene glycol/SiO 2 nanocomposite was synthesized via free radical polymerization technique in inert nitrogen gas atmosphere. Prior to the polymerization process silica nanoparticles were dispersed completely by stirring an aqueous solution of silica nanoparticles for 30 min in ultrasonic bath (Fisherband model FB 15101, UK) at room temperature.

- What are polyacrylamide (PAM) soil amendments?
- Degraded lands resulting from human and natural causes are widespread in arid and semiarid regions throughout the world. Polyacrylamide (PAM) soil amendments are increasingly used to remediate these degraded lands with the potential benefits on soil health and crop production.
- 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.
- 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.
- Does polyacrylamide reduce water usage?
- The well as reduced water usage. Polyacrylamide is economical problem areas in a field. Po lyacrylamide is effective in reducing runoff, erosion, and soil sealing. The construction industry has a great potential for PAM use. Whether used erosion. The potential for PAM use in erosion control properties of PAM and its interaction with soil.
