degradation of polyacrylamide and its significance in nature
the hydrolyzed form of polyacrylamide (hpam), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic pam in oil and gas development as well as in soil conditioning.
the impact of high-quality polyacrylamide soil conditioner on soil,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
acute and long-term effects of anionic polyacrylamide apam
they can occur in non-ionic form, or as polyelectrolytes in cationic (cpam) and anionic (apam) form and are produced in various molecular weights depending on their intended application. pam are widely used in industrial processes, amongst others to aid flocculation and complexation (biesinger et al., 1976; bolto and gregory, 2007).
polyelectrolyte polymers—types, forms, and function,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 polyacrylamide in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (phpa), although they are in actuality copolymers [80]. both

- Does Pam solvated with Fe 3+ release acrylamide?
- It was found that PAM solvated with Fe 3+ generated ppb levels of acrylamide after exposure to sunlight under acidic conditions (pH 6). They concluded that release of acrylamide would be insignificant at low levels of iron (0.02 mg/L) under alkaline (7.5–8.5) conditions.
