role of polyelectrolytes in the treatment of water for free sample
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 ).
optimization conditions to obtain cationic polyacrylamide,we successfully synthesized three cpam emulsions with a wide range of cationic degrees: low (21.85%), medium (40.25%), and high (71.17%) levels of cationic degree. the optimized conditions for these cpams were as follows: monomer concentration of 25%, content of monomer cation of 22.5%, 44.41%, and 77.61%, respectively, and initiator content of
application of polyelectrolytes for contaminant removal for free sample
1. introduction. polyelectrolytes are a type of water-soluble polymer with a multitude of ionizable groups. the combination of their polymeric characteristics and ionizable behaviour give polyelectrolytes various useful properties, and thus they offer a broad spectrum of applications in a wide variety of fields, including but not limited to pharmaceuticals, biomedicine, medicine, petroleum
polyelectrolytes as a material of value in water treatment a,the paper presents the application of some inorganic coagulant, i.e. ferric sulphate and polymeric flocculants, such as: anionic polyelectrolyte, ponilit gt-2 and cationic polyelectrolyte
addressing water scarcity: cationic polyelectrolytes in water
in this review, we elaborate recent advances in cationic polyelectrolyte (cpe) synthetic methods used for several types of water treatment and characterization techniques of both cpes and aggregated impurities. cpes effectively coagulate and flocculate impurities in wastewater from human usage and mining, papermill, textile and farming industries.

optimizing the conditions of cationic polyacrylamide inverse
from the verified experiments combined with the models, the optimal conditions for the cationic inverse emulsion synthesis to achieve high average molecular weight and high conversion are as follows: stirring speed of about 2500–2600 rpm, reaction temperature of 60–62 °c, and reaction time of 7 h.
green photocatalytic route to synthesize cross-linked,as one of the most important flocculants, polyacrylamide (pam)-based materials show enhanced capability to purify highly turbid wastewater treatment prolonging the length of molecular chains and modifying functional groups, which, however, generally involves complex synthetic procedures and expensive functional guests. in this study, exfoliated g-c3n4 colloids (cncs) were used as sunlight-driven
