degradation of polyacrylamide and its significance in nature
high quality flocculant polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction enhancer.
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
