    The difference of anionic, cationic and Non-ionic

    Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide

    Anionic polyacrylamide - wastewater treatment chemicals

    Description. Anionic polyacrylamide is the kind of wastewater treatment chemicals which is water-soluble linear polymer synthesized with high degree of polymerization.Anionic polyacrylamide powder is easily soluble in water and almost insoluble in common organic solvents such as benzene, ether, lipids and acetone. Anionic polyacrylamide molecular chain contains a certain amount of polar groups

    Cationic polyacrylamide copolymers (PAMs): environmental

    Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer’s fate in the soil compartment, the degradation of 14C-radiolabelled

    ANIONIC POLYACRYLAMIDE. Composition: Negatively charged copolymers of acrylamide are widely used as retention aids and dry-strength resins. However, different molecular mass ranges are used for these two roles. Anionic acrylamide copolymer retention aids typically have molecular masses in the range of 5 to 20 million grams per mole.

    Synthesis, Characterization, and Flocculation Properties

    Abstract. A water soluble branched cationic polyacrylamide (BCPAM) was synthesized using solution polymerization. The polymerization was initiated using potassium diperiodatocuprate, K 5 [Cu(HIO 6) 2](Cu(III)), initiating the self-condensing vinyl copolymerization of acrylamide and acryloxyethyltrimethyl ammonium chloride (DAC) monomer.The resulting copolymer was characterized by the use of
