bangladesh polymer chemical polyacrylamide quality polyacrylamide

polyacrylamide, or pam, is an organic polymer formed from polyacrylamide sub-units. initially, it is produced with a simple, repeating, linear chain structure, but can be modified to form highly structured, branched and cross-linked variants. it has many uses throughout a wide range of industrial processes, but one of the main purposes is in the.

polymers for coagulation and flocculation in water treatment,a common example is anionic polyacrylamide. the anionic natural polymers are the sulphated polysaccharides or their derivatives, which include heparin, dextran sulphate, mannan sulphate, alginates, carrageenans, gellan, gum arabic and xanthan and chondroitin sulphate. these anionic polysaccharides found application more in medicine than in the

enhanced polyacrylamide degradation via oh radical-initiated

hydroxyl (oh) radicals, as common radicals in aqueous environments, play an important role in inducing the degradation reactions of polymers. however, understanding the fundamental mechanisms of radical-induced degradation of polymers at the atomic level remains a formidable challenge. in this study, we employ density functional theory to investigate the geometric and electronic structural

electrostatic interactions in dissipative particle dynamics

as an example of this simulation tool, the interaction between a cationic polyelectrolyte and anionic surfactant is discussed. without a surfactant, the polyelectrolyte shows a fractal dimensionality that is in line with the theoretical and experimental values cited in literature, it behaves as a fairly stiff rod, d f ∼1.1.

  • Which polyelectrolytes are used in Wat R treatment?
  • onic and anionic polyelectrolytes are more commonly used in wat r treatment. Polymers with no charged group are known as non-ionic polymers. Literature review reveals tha
  • What are anionic and cationic groups of polyelectrolytes?
  • Anionic groups include carboxylate and sulphonate, while cationic group is quaternary amine. The structure of amine is similar to NH 3 but is protonated to give NH 4+ but with R group instead of H attached to nitrogen. R is any hydrocarbon. Functional group of polyelectrolytes with anionic and cationic charge
  • Which polyelectrolyte is used in water treatment?
  • Synthetic polyelectrolyte namely non-ionic PAM has also been used in water treatment (Selvapathy and Reddy 1992 ). It consists of 1–3% anionic group as in case of PAM, where they are prepared by hydrolysis of amide groups under controlled conditions.
  • What are non ionic polyelectrolytes?
  • Natural non-ionic polyelectrolytes are starch, cellulose derivatives, gelatins and glues. Their structure, molecular weight, biodegradability and ease of dissolution are found to be different. Synthetic polyelectrolyte namely non-ionic PAM has also been used in water treatment (Selvapathy and Reddy 1992 ).
