Polyacrylamide degradation and its implications
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
The use of cationic, anionic and nonionic polyacrylamide. Polyacrylamide (PAM) is a linear water soluble polymer, is a water-soluble polymer compounds used in wide varieties of one, PAM and its derivatives can be used as efficient flocculant, thickening agent, paper strengthening agent and liquid drag reduction agent, which is widely used in water treatment, paper, petroleum, coal, mining, metallurgy, geology, textile, construction and other industrial sectors.
The role of cationic polyacrylamide in the reverse
The reverse flotation separation of kaolinite and diaspore has been achieved by using the collector dodecylamine (DDA) and depressant cationic polyacrylamide (CPAM) at pH 5.5–8.5.
Cationic polyacrylamide (CPAM) is a type of polyelectrolyte that has been widely used as a sludge conditioner because of its low dosage requirement, high efficiency, and pollution-free effects. Previous studies report that CPAM dosage is critical in sludge conditioning because overdoses increase cost and deteriorate sludge dewaterability [12] .

A novel method for one-step preparation of antifouling ultrafiltration membranes via a non-solvent induced phase separation (NIPS) technique is proposed. It involves using aqueous 0.05–0.3 wt.% solutions of cationic polyelectrolyte based on a copolymer of acrylamide and 2-acryloxyethyltrimethylammonium chloride (Praestol 859) as a coagulant in NIPS.
Putative role of cationic amino acid transporter‐3
To the Editor: With great interest I read the article by Gu et al., revealing a role of cationic amino acid transporter‐3 (CAT‐3) in the regulation of hepatic fatty acid oxidation in zebrafish through nitric oxide/adenosine monophosphate–activated protein kinase/peroxisome proliferator–activated receptor‐α signaling. 1 The authors report that they also knocked down the zebrafish

Cationic glyoxalated polyacrylamide Glyoxalated polyacrylamide (GPAM) is widely applied in a variety of paper grades to increase paper dry strength. GPAM is typically added in the pulp suspension before paper sheet formation. Upon drying the treated paper sheet, GPAM is believed to form covalent bonds with cellulose to increase paper dry strength.
Polyacrylamide is a polymer, which is formed by the synthesis of acrylamide subunits. This is widely used in water treatment and papermaking. Polyacrylamide plays a vital role in the wastewater management. Therefore, the rising environmental concerns for the water management increase the usage of polyacrylamide.
- Can polyacrylamide be used as a soil conditioner?
- The favorable effects of the environmentally friendly, nontoxic, anionic polyacrylamide (PAM) as a soil conditioner have long been established. Some uncertainties exist, however, regarding the effects of PAM molecular weight (MW) on its performance as a soil amendment and its ability to penetrate into aggregates and stabilize interior surfaces.
- What is ionic polyacrylamide (PAM)?
- Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration.
- Is Pam a soil conditioner?
- PAM is currently used as a soil conditioner on ~800,000 ha 33 of irrigation land in the U.S., corresponding to 900–18,000 tons of PAM per year. PAM binds with soil particles through electrostatic interactions forming aggregates that prevent irrigation-induced erosion and increase the hydraulic conductivity of the soil.
- Does adding anionic polyacrylamide improve soil aggregation?
- Adding anionic polyacrylamide (PAM) to soils stabilizes existing aggregates and improves bonding between and aggregation of soil particles. However, the dependence of PAM efficacy as an aggregate stabilizing agent with soils having different clay mineralogy has not been studied.
