Polyacrylamide degradation and its implications in environmental

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. 1,...

Polyacrylamide Soil Conditioners: The Impact on

Nonionic polyacrylamide has a strong hydrophilic character, greater than other nonionic, water-soluble polymers. Despite being described as nonionic synthetic polyacrylamides obtained as a result of polymerization or copolymerization of acrylamides, often contain in their macromolecules about 1¨C3% of anionic groups [ 4 ].

Regarding the two cases of anionic and nonionic PAMs, the settling performance of maturated floc aggregates formed by anionic PAM seemed to be worse than those formed by nonionic PAM for the coagulant dosage of either 1.0 or 2.5 mg Al/L, reflected by a somewhat higher residual turbidity of settled water for anionic PAM relative to nonionic PAM at the same sedimentation times (Fig. 3 a and b).

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide, is highly water soluble, cost-effective, and very

Polyacrylamide

From Wikipedia, the free encyclopedia Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1]

Then, nonionic polyacrylamide (5 wt%) was added and stirring was continued for a few minutes to finally obtain a 10 wt% NPAM/poloxamer mixture. After sonication to remove air bubbles, the product was freeze-dried to obtain a powder. Cationic polyacrylamide and anionic polyacrylamide were prepared using the same method.

Impact of anionic polyacrylamide on stability and surface properties

The stability mechanism and thermal properties of the system alumina¨Canionic polyacrylamide (PAM) was studied. The polymer¡¯s adsorption properties in dependence on the following parameters solution pH (in the range 3¨C9), temperature (in the range 15¨C35 ¡ãC), and carboxyl groups¡¯ content in the PAM chains (in the range 5¨C30 %) were examined.
