What is anionic polyacrylamide?

Anionic polyacrylamide is a kind of White or yellow powder,non-toxic,non-corrosive,easily solubale in water,mainly used as a selective flocculant for non-dispersed,low solid phase water-based drilling fluid.itcan help to reduce water losses,improve drilling fluid rheological properities and reduce the friction resistance as well. 3. Application

What is the use of polyacrylamide in oil drilling?

For oil drilling, liquid or powder partially-hydrolyzed polyacrylamide is used as additives to water based drilling mud to provide a lubricating film and reduce friction at the drill bit, impart stability to shale and clay and increase viscosity [ 1, 22, 26 ].

What are the advantages of anionic polyacrylamide?

The use of anionic polyacrylamide increases the flocculation efficiency of the coagulant, increasing the settling speed, reducing the amount of coagulant required for the treatment and lowering the cost of the coagulation-flocculation process. This work was financially supported by a grant from the Ministry of Education and Science of Spain.

Can anionic polyacrylamide be used as a mediator in environmental remediation?

Uncovering an accessible and cheap material as mediator becomes a top priority, which can potentially improve the activity of heterojunction in environmental remediation. Anionic polyacrylamide (APAM) is a hydrophilic polymer which is easy to be carbonized (Choi et al., 2004).
