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 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.

What is a high molecular weight anionic polymer flocculant?

High molecular weight anionic polymer flocculant. Accepta 2047 is a superior quality anionic high molecular weight latex emulsion polyacrylamide co-polymer for effluent and wastewater treatment.

What is template polymerization and ultrasonic initiation system of anionic polyacrylamide (TPAs-U)?

In this study, template polymerization and ultrasonic initiation system attributed to the self-assembly of anionic polyacrylamide (TPAS-U) with a microblock structure using acrylamide (AM) and sodium p-styrene sulfonate (SSS) as monomers and poly (allylammonium chloride) (PAAC) as template.

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.

Does TPAs-U microblock structure improve flocculation performance in hematite wastewater treatment?

Flocculation performance of TPAS-U with microblock structure in the treatment of hematite wastewater were compared with other anionic flocculants in terms of turbidity removal, zeta potential, the breakage and regrowth of flocs and settling property of flocs. Flocculation mechanism was illustrated for more details.
