What are polyacrylamides (Pam)?

Polyacrylamides (PAM) are synthetic polymers available in both powder and liquid (emulsion) form (Needham & Doe, 1987; Chang, 1978; Donaldson et al., 1989). These polymers are manufactured in a variety of ways to yield a wide range of physical and chemical properties that make them candidates for many different oilfield applications.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (APAM) is a hydrophilic polymer which is easy to be carbonized (Choi et al., 2004). The amide group (−CONH 3) on APAM can form hydrogen bond with the uncondensed amine groups on surface of g-C 3 N 4 (Schwinghammer et al., 2014).

What are the different types of polyacrylamide?

Polyacrylamide comes in various forms such as granular, liquid oil emulsion, tablet, and block forms. Dry polyacrylamide is easier to store, transport, and meter into head ditches and they also have a longer shelf life than liquid forms. However, liquid forms require less agitation to dissolve.

What is Pam used for?

It is used in the floatation and smelting of zinc, manganese and copper mines, its leachate and slag can be added into PAM to improve the separation efficiency. It is used in coal mining industry for waste water, coal washing waste water clarifier.

Why is polyacrylamide used in paper making industry?

Polyacrylamide can be used for paper making industry to improve the dry and wet strength, increase stability of pulp, enhance the staying rate of filling material and speed size filterability in the paper. It is also used to treat wastewater in the paper industry.

What is polyacrylamide used for?

Polyacrylamide is widely used to flocculate or coagulate solids / suspended particles in various types of wastewater, such as municipal sewage, dyeing, leather, industrial wastewaters. Polyacrylamide is used in irrigation water in agriculture to improve soil texture, sugar refining, where it can be used in beet or cane juice clarification.
