- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
- Is polyacrylamide a comonomer?
- Polyacrylamide (PAM) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers.
