What is a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.

Which polyacrylamide is used as a pulp dispersant?

Anionic polyacrylamide can be used as a pulp dispersant. Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater.

What are the applications of polyacrylamide (PAM)?

As a result, PAM is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields. Polyacrylamide is mainly used in the flocculation, sedimentation, and dewatering processes in municipal wastewater treatment.

What is the purity of polyacrylamide (PAM)?

The polyacrylamide (PAM) was obtained from Sigma-Aldrich, with purity > 99%. The Direct Blue 78 (DB78) with the commercial name Tubantin GLL 300 has a molecular weight of 1059.95 g/mol and a maximum wavelength (λ max) of 604 nm. It is soluble up to 10 g/L at 25 °C and is commonly used in the textile industry.

What is polyacrylamide used for?

And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry. In food industry, it is used for cane juice clarification and syrup phosphorus floatation extraction in the production of cane sugar and beet sugar.

Is polyacrylamide a water soluble polymer?

Polyacrylamide (PAM) is a water-soluble linear high-molecular polymer formed by the polymerization of acrylamide monomers initiated by free radicals. At the same time, it is also a kind of polymer water treatment flocculant.
