polyacrylamide

Polyacrylamide

Polyacrylamide (IUPAC poly(2-propenamide) or poly (1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide. In the cross-linked form, the possibility of the monomer being present is reduced even further. It is highly water-absorbent, forming a soft gel when hydrated, used in such applications as polyacrylamide gel

Introduction to Polyacrylamide Gels | LSR | Bio-Rad

Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below). Riboflavin (or riboflavin–5'–phosphate) may also be used as a source of free radicals, often in combination with TEMED and APS. Polymerization speed depends on various factors (monomer and catalyst concentration, temperature and

Isolation and Characterization of Polyacrylamide-Degrading Bacteria

Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces hazardous monomers. In the present study, the bacterial strain HI47 was isolated from dewatered sludge. This strain could metabolize PAM as its sole nutrient source and was subsequently identified as Pseudomonas putida. The efficiency of PAM degradation was 31.1% in 7 days and exceeded 45% under

Most acrylamide is used to synthesize polyacrylamides, which find many uses as water-soluble thickeners. These include use in wastewater treatment, gel electrophoresis (SDS-PAGE), papermaking, ore processing, and the manufacture of permanent press fabrics. Some acrylamide is used in the manufacture of dyes and the manufacture of other monomers.

Preliminary study of acrylamide monomer decomposition during methane

Polyacrylamide (PAM) used in sludge dewatering exists widely in high-solid anaerobic digestion. Acrylamide is registered in the list of chemicals demonstrating toxic, carcinogenic and mutagenic properties. Therefore, it is reasonable to ask about the mobility of such residual substances in the environment. The study was carried out to assess the impact of the mesophilic (39 ± 1°C) and thermophilic (54 ± 1°C) fermentation process on the level of acrylamide monomer (AMD) content in the

Polyacrylamide is homopolymer of acrylamide monomer

Polyacrylamide is a kind of linear polymer, which can be homopolymerized (partially hydrolyzed) by acrylamide monomer or copolymerized with other functional monomers (such as AA, DAC, DMC, etc.) in different proportions. There are a lot of side acylamino groups in the main chain of its molecule. Amido group is very active and can react with many compounds to produce many polyacrylamide derivatives. In this way, polyacrylamide not only has a series of derivatives, but also has a variety of

Application Of Polyacrylamide PAM Flocculant In Textile Waste Water Treatment Industry. Nov 09, 2019. In the textile printing and dyeing industry, a large amount of water is usually used. After use, the water will contain a lot of harmful substances, which cannot be directly discharged. The printing and dyeing wastewater has a large amount of water, and each printing and dyeing process consumes 100 to 200 tons of water per ton of textiles. 80 to 90% of them become wastewater.

The results also showed that the increase in the intrinsic viscosity and glass transition temperature were proportional to the increase in molecular weight of polyacrylamide. On the other hand it can be seen an increase in molecular weight caused a decrease of weight loss %. Keywords:polyacrylamide
