electrolytic manganese metal production from manganese

Electrolytic manganese metal production from manganese

The addition of polyacrylamide polymer can significantly improve the manganese deposit quality. A compact manganese deposit can be produced with an improved current efficiency at an appropriate dosage. At a dosage above a certain value, the manganese deposit cracked due to the increased internal tensile stress.

A novel double-network hydrogel made from electrolytic

Electrolytic manganese slag (EMS), a bulk waste generated in industrial electrolytic manganese production, can be a cost-effective adsorbent for heavy metals removal after appropriate modification. In this study, EMS was activated by NaOH and then used to make the EMS-based double-network hydrogel (an EMS/PAA hydrogel) via a one-pot method.

Polymers for conformance improvement - PetroWiki

Because pure polyacrylamide is slightly positively charged (cationic) in an acidic or "neutral" pH environment, polyacrylamide tends to adsorb onto reservoir rock surfaces, especially sands and sandstone pore surfaces. For these reasons, partially HPAM is most often favored for use in polymer flooding.

Exploring Alternatives to Polyacrylamide: A Comparative Study

The new polymer flocculants performed better than the commercially available polyacrylamides but retained high amounts of water in the sediments. This comparison shows that polymers other than polyacrylamide may be used to treat iron ore tailings.

Polyacrylamide

[1] Copolymers and modified polymers [ edit] Linear polyacrylamide is a water-soluble polymer. Other polar solvents include DMSO and various alcohols. Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels .

UltraPure? Acrylamide - Thermo Fisher Scientific

UltraPure? Acrylamide is a major ingredient in polyacrylamide gels, which are used for electrophoretic separation of both nucleic acid fragments and proteins. DNA fragments generated by restriction endonuclease digestion, dideoxy sequencing, or the Maxam and Gilbert sequencing methods can be separated by polyacrylamide gel electrophoresis (PAGE).

Polyacrylamide degradation and its implications

The term ¡°polyacrylamide¡± is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which defines...

Polyacrylamides (PAMs) are relatively inexpensive polymers that are easily formulated to high molecular weights on the order of several million g/mol. PAM was first used in the paper industry in the mid-1950s.

biodegradation of anionic polyacrylamide by manganese

Biodegradation of anionic polyacrylamide by manganese

Manganese peroxidase (Mn P) is capable of effectively degrading anionic polyacrylamide (HPAM). However, the interaction of Mn P with HPAM at molecular level is lacking until now. Here, the HPAM model compounds, HPAM-2, HPAM-3, HPAM-4, and HPAM-5, were selected to reveal their binding mechanisms with Mn P. The results showed that the most suitable substrate for Mn P was HPAM-5, and the main
