- 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 polyacrylamide structure affect flocculation of bentonite clay?
- Shaikh and coworkers studied the effect of polyacrylamide structure on the flocculation of bentonite clay. 208 Using turbidity as a powerful measure, they compared flocculations using cationic, anionic, and amphoteric polyacrylamides of varying molecular weights.
- Which polymers are used in TPAs-U self-assembly of anionic flocculants?
- In this study, the novel template polymerization and ultrasonic initiation system were applied in the self-assembly of anionic flocculants (TPAS-U) using poly (allylammonium chloride) (PAAC) as template, acrylamide and sodium p-styrene sulfonate as monomers.
