The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers [80] .

ANIONIC POLYACRYLAMIDE - Santos

Synonyms: Anionic polyacrylamide 3 PHYSICO-CHEMICAL PROPERTIES Polyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polymerisation of acrylamide. Anionic polyacrylamide polymer can then be formed from the hydrolysis of the

In a more precise classification, if the charges are introduced by copolymerizing cationic and anionic monomers, the polymer is called amphoteric, whereas if the polymer is made of a monomer that has both cationic and anionic groups (overall zero charge), it is called zwitterionic or betaines. 40 Comprehensive reviews on this special class of polymers can be found elsewhere. 40-43 The use of

Comparison of adsorption affinity of anionic and cationic

The ionic polyacrylamide and Cr(VI) ions amounts adsorbed on the montmorillonite surface are presented in Figs. 3 and 4. These values depend largely on the solution pH. The adsorbed amounts of cationic PAM increase with the pH decrease (higher adsorption of CT PAM is observed at pH 7 than 5). The pK b value for the cationic polyacrylamide is 9.

Polyacrylamide Soil Conditioners: The Impact on

The polymer adsorption increases with the following order: anionic PAM < nonionic PAM < cationic PAM . 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

Characterization of the adsorption of high molecular weight non-ionic

High molecular weight, anionic, non-ionic and cationic polyacrylamide are used extensively in the oil industry in applications such as drilling, water shut-off, and enhanced oil recovery. They are also used as flocculants in water treatment processes.

Flocculation behaviour and mechanisms of cationic inorganic

the inorganic CM (colloidal alumina) show limited effectiveness in inducing fine clay flocculation. However, a synergetic effect is observed between anionic polyacrylamide and CM. ? In conjunction with cationic and non-ionic polyacrylamides, good clay flocculation is observed, but with little synergy between each component. ?
