degradation of polyacrylamide and its significance in nature
high quality flocculant polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction enhancer.
recent achievements in polymer bio-based flocculants for sale,the flocculants, designed for coal slime water treatment, were characterized using the ftir, xrd and sem methods. it has been shown that water turbidity was reduced by ~97% and ~94%, while cod removal was ~78 and ~74% in the presence of fe 3 o 4 -chitosan-cellulose and fe 3 o 4 -chitosan-biochar, respectively.

cationic polyelectrolyte vs. anionic polyelectrolyte. cationic and anionic polyelectrolytes are two forms of water-soluble polymers that differ principally in charge properties and use. cationic polyelectrolyte. cationic polyelectrolytes have a positive charge along their molecular chains because they include ammonium or other positively
application of flocculants in wastewater treatment,this amino-biopolymer possesses several intrinsic characteristics such as high cationic charge density (due to the presence of primary amino groups) (guibal and roussy, 2007) and long polymer chains with high molecular weight, thus make it an effective coagulant and/or flocculant for the removal of contaminants in the suspended and dissolved
preparation of polyacrylamide with high relative molecular
polyacrylamide (pam) with high molecular weight was synthesized by microemulsion method. polyacrylamide was used as monomer, and a self-made initiator was used for polymerization under the condition of coexistence with sodium carbonate. the optimal polymerization parameters of pam are determined: ph value of solution was 12. 3.

- Which Polyelectrolytes have both cationic and anionic repeat groups?
- Polyelectrolytes that bear both cationic and anionic repeat groups are called polyampholytes. The competition between the acid-base equilibria of these groups leads to additional complications in their physical behavior. These polymers usually only dissolve when sufficient added salt screens the interactions between oppositely charged segments.
- Why do polyelectrolytes react with other species of opposite charge?
- The charged nature of polyelectrolytes allows for reaction with other species of opposite charge (charge neutralization) . The concept of charge neutralization is relatively straightforward. The charge of a polymer chain interacts with the charge of the substrate, thus neutralizing the charge.
- What is the difference between cationic and anionic polymerization?
- The main difference between cationic and anionic polymerization is that cationic polymerization is initiated by a cationic species, whereas anionic polymerization is initiated by anionic species. Polymerization is a chemical process in which small molecules called monomers react with each other to form long chains or networks known as polymers.
- Are polycations and polyanions electrically conductive?
- Polycations and polyanions are polyelectrolytes. These groups dissociate in aqueous solutions (water), making the polymers charged. Polyelectrolyte properties are thus similar to both electrolytes ( salts) and polymers (high molecular weight compounds) and are sometimes called polysalts. Like salts, their solutions are electrically conductive.
