Cationic polyacrylamide copolymers (PAMs): environmental half life

Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).

Comparison of adsorption affinity of anionic and cationic

The first one¡ªanionic polyacrylamide (AN PAM) contained 30% of the ionizable carboxyl groups whereas the cationic polyacrylamide (CT PAM)¡ª35% of the quaternary amine groups. The average molecular weight of the adsorbate was equal to 13,000 and 7000 kDa, respectively.

Water Soluble Polymer Flocculants: Synthesis, Characterization,

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative number of sites vary depending on surface charge

polyacrylamide soil conditioners: the impact on

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 [ 80 ], whereas cationic or anionic forms adsorb and bind soil particles through electrostatic forces or bridge formation between PAM charged moieties and solid surface group [ 1 , 80 ].

Two samples of ionic polyacrylamide PAM (Korona JV)¡ªthe anionic (AN PAM) and cationic (CT PAM) forms were applied as the adsorbates in the study. They differ from each other in the weight average molecular weight and ionic groups content¡ª15,500,000 Da and 50% for AN PAM, as well as 7,000,000 Da and 80% for CT PAM.

Effect of polyacrylamide polymers on floc size and rheological

The influence of cationic and anionic polyacrylamides (PAM) on the floc size, compressive yield stress, and rheological behaviour of kaolinite suspensions has been investigated at pH 7. At optimum polymer concentrations, the kaolinite floc sizes were larger in the presence of anionic PAM than cationic PAM.
