Flocculants - an overview | ScienceDirect Topics
In wastewater treatment, polyacrylamide-based flocculants are commonly used. Because they can contain potentially toxic acrylamide residues, flocculants based on natural biopolymers are preferred over synthetic polymers. An effective biopolymer flocculant for harvesting microalgae is chitosan, which is prepared by deacetylation of chitin.
Novel biodegradable polymeric flocculants were produced by conventional redox grafting, microwave-initiated and microwave-assisted grafting of acrylamide to tamarind kernel polysaccharide (TKP). The graft copolymers were characterized by viscometry, elemental analysis, molecular weight determination using SLS analysis, and NMR spectroscopy.

The present article deals with the recent developments which took place in authors’ laboratory on the synthesis of novel cationic flocculants based on modified polysaccharides derived from starch, amylose, amylopectin, chitosan, guar gum, glycogen, and tamarind kernel. The applications of these modified polysaccharides as flocculants for the treatment of various wastewaters including municipal sewage wastewater and as adsorbent for removal of reactive black dye from its aqueous solution
The aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (PAM)-based flocculants Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter.
Nanostructured Dextran-Graft-Polyacrylamide Flocculants
The degree of supernatant clarification for branched polymers at optimal flocculant concentrations was higher than for linear PAA. Branched and linear flocculants in anionic form were tested and compared with respect to flocculation for kaolin dispersion setting as well as for efficiency at removing Cu 2+ , Co 2+ , and Ni 2+ ions during the
A novel organic polymeric flocculant was syn- thesized by grafting cationic etherifying mono- mer (3-chloro-2-hydroxypropyl) trimethyl ammo- nium chloride (CHPTAC) onto the backbone of corncob powder (CP, Φ ≤ 30 µm). The synthetic reaction between CP and CHPTAC was initiated by hydroxyl radical made from Fenton reagent (H 2O 2-FeSO 4). The alkalization process and syn-
- How do you make a polyacrylamide gel?
- Prepare a 5x stock solution in 1 liter of H2O. The 1×working solution is 25 mM Tris-Cl/250 mM glycine/0.1% SDS. Use Tris-glycine buffers for SDS-polyacrylamide gels. 55°C. Assemble the glass plates according to the manufacturer’s instructions. Determine the volume of the gel mold (this information is usually provided by the manufacturer).
- What is a polyacrylamide gel?
- Polyacrylamide gels are composed of a mix of polyacrylamide and bis-acrylamide, which form a crosslinked polymer by the polymerizing agent ammonium persulfate (APS) and the catalyst TEMED (N,N,N,N´-tetramethylenediamine).
- How is native polyacrylamide gel electrophoresis performed?
- Native polyacrylamide gel electrophoresis is performed using 6% acrylamide gels in Tris‐boric‐EDTA (8.9 m M Tris base, 8.9 m M boric acid, 0.2 m M Na 2 EDTA) buffer, pH 8, as described by Laemmli (1970). Staining for GSNOR activity is carried out using a modification of the method reported by Seymour and Lazarus (1989) and Fernández et al (2003).
- What is non-denaturing polyacrylamide gel electrophoresis (native PAGE)?
- Non-denaturing polyacrylamide gel electrophoresis (Native PAGE) is the polyacrylamide gel electrophoresis of proteins without the addition of denaturants such as SDS.
