degradation of polyacrylamide and its significance in nature
acrylamide at a dose of 20 mg/kg/day stimulated the degeneration of peripheral nerves and the spinal cord of rats, although no obvious effects were found at doses less than 0.2 mg/kg/day. 152
sewage treatment chemical additives polyacrylamide powder,polyacrylamide is widely used in municipal wastewater, industrial wastewater treatment,and drinking water treatment from rivers and lakes. The adsorption and decolorization properties of polyacrylamide are commonly used in the papermaking, printing and dyeing, textile and leather production industries.
the impact of high-quality polyacrylamide soil conditioner on soil
polyacrylamide is a water-soluble synthetic polyelectrolyte which consists of repeating units (forming a chain structure and containing hydrophilic groups). due to the different nature of the groups present in the macromolecules, polyacrylamide can be divided into nonionic, anionic, and cationic ones.

what is partially hydrolyzed polyacrylamide (phpa. phpa is a white granular powder, anionic in nature having a specific gravity of 1.25 to 1.40 and a bulk density of 40 to 46 lb/ft 3. phpa influences cuttings and wellbore stability and enhances solids removal by flocculation.
the effect of cations on the activity of anionic,to this end, inlet slurry to the tailings thickener of the gol-e-gohar iron ore processing plant was sampled for four days. flocculant type (anionic, cationic, and nonionic polyacrylamide), their dosage (10–90 g/t), ph (1–12.5), solid content (5–23%), and for the first-time residual flocculant dosage in the circulated water were investigated.
- How do SDS-coated proteins migrate in a sieving polyacrylamide gel?
- In a sieving polyacrylamide gel, the rate at which the resulting SDS-coated proteins migrate in the gel is relative only to their size and not to their charge or shape Protein detection technology involving UV-induced haloalkane modification of protein tryptophan residues.

- How are polyacrylamide gels made?
- Polyacrylamide gels are cast using mixtures of acrylamide monomers with a cross-linking reagent, usually N,N'-methylenebisacrylamide (bis), both solubilized in buffer Relative distance a protein has traveled compared to the distance traveled by the ion front. This value is used to compare proteins in different lanes and even in different gels.
