- 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.
- Which polyacrylamide polymers are more efficient under acidic pH?
- In addition, the efficiency of the anionic G.Eudoxie and S.E. Hitlal: Efficiency of Polyacrylamide Polymers in Settling Aggregate Mining Tail Water 61 PAM has been shown to be greater under acidic pH (Deng et al., 2006). The effectiveness of the flocculation process depends on both the nature of the flocculant as well as suspension properties.
- 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.
- What spectroscopy is used to identify anionic polyacrylamide flocculant?
- The anionic polyacrylamide (APAM-T) flocculant was characterized by Fourier transform infrared spectroscopy (FTIR), 1 H nuclear magnetic resonance spectroscopy ( 1 H NMR), and scanning electron microscopy (SEM). Furthermore, the X-ray photoelectron spectroscopy (XPS) was conducted to measure the elemental composition.
