  • What is nonionic polyacrylamide (NPAM) gel?
  • Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
  • Which polymers are used in water treatment?
  • The polymers investigated were nonionic polyacrylamide (NPAM), anionic polyacrylamide (APAM) and cationic polyacrylamide (CPAM). This is because polyacrylamide-based polymers are commonly used in various water treatment industries [ 9, 31, 32, 33, 34 ].
  • 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 are the different types of polyacrylamide adsorption polarities?
  • Specifically, it can be divided into non-ionic polyacrylamide (NPAM), anionic polyacrylamide (APAM), and cationic polyacrylamide (CPAM). C 3 H 7 ON, C 3 H 6 O 2, and C 5 H 9 O 2 N + are the basic structural units of these PAM, resulting in different adsorption polarities [ 12, 13 ].
