Polyacrylamide in Agriculture and Environmental Land Management

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation©induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms

Research on a new cationic polyacrylamide (CPAM) with a cationic microblock structure and its enhanced effect on sludge condition

Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge. Therefore, it is particularly important to develop new and efficient flocculants

polyacrylamide

Polyacrylamide

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.

Adsorption of cationic polyacrylamide onto kaolinite

According to the experimental results, the adsorption of PAM increases with pH from 5.50 to 10.50; temperature from 25 to 55 ¡ãC and ionic strength from 0 to 0.1 mol L ?1. The kaolinite sample calcined at 600 ¡ãC has a higher adsorption capacity than the other calcined samples.

Using Polyacrylamide (PAM) to Reduce Erosion on Construction Sites - NC State Extension Publications

PAM is a term describing a wide variety of chemicals based on the acrylamide and acrylate units. When linked in long chains, these units can be modified to result in a net positive, neutral, or negative charge on the PAM molecule. The positively charged, or cationic, PAMs, are not used for erosion control because they can be toxic to fish and

Polyacrylamide Soil Conditioners: The Impact on Nanostructured Clay Minerals¡¯ Aggregation and Heavy Metals¡¯ Circulation in the 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 [ 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 ].
