polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

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. [1] Physicochemical properties [ edit]

biodegradation of the cross-linked copolymer of acrylamide

Biodegradation of the cross-linked copolymer of acrylamide

Chemical cross-linking and the high molecular weight of superabsorbent copolymers (SAPs) are the two main causes of their resistance to biodegradation. However, SAP particles are colonized by microorganisms. For the purposes of this study, the dry technical copolymer of acrylamide and potassium acrylate containing 5.28 % of unpolymerized monomers was wrapped in a geotextile and incubated in

Rapid Degradation of Superabsorbent Poly(Potassium Acrylate

Superabsorbent polymers (SAPs) are basically the hydrophilic three-dimensional network of water-insoluble polymer chains that can absorb fluids such as water, electrolyte solution, and biological fluids as high as 1000 g/g of their own dried weight whereas the absorption capacity of common cotton pulp is not more than 1 g/g [1, 2].

Potassium persulfate (K 2 SO 4) is commonly used as a source of free radicals to drive acrylamide polymerization. Nitrates of potassium, sodium, silver (I), copper (II), and iron (III) were used to investigate the influence of NO 3 ? and transition metal ions, respectively, while silver (I) fluoride was also used to assess the impact of

In this work, we proposed a flexible and durable potassium polyacrylate (PAAK)¨CKOH gel polymer electrolyte (GPE) prepared in a very simple way to solve the above problems of the Zn anode. The obtained highly porous gel electrolyte showed higher water retention, satisfying ionic conductivity (0.918 S cm ¨C1 ), and a broad electrochemical

Analysis of Acrylamide in a Complex Matrix of Polyacrylamide

When polyacrylamide solution was heated at 70 ¡ãC for 16 h with 0.5% potassium persulfate, the amount of acrylamide increased to 1.02 ¡À 0.11 ¦Ìg/mL. When polyacrylamide solution was irradiated by UV (¦Ë = 300 nm) for 16 h with 0.05% 2-anthraquinone sulfate sodium salt, the amount of acrylamide increased to 1.14 ¡À 0.54 ¦Ìg/mL.
