synthesis and characterization of amphoteric polyacrylamide

amphoteric polyacrylamide (ampam) carries anionic and cationic charge group on the polymer back-bone, which can adsorb both organic and inorganic sus-pension substances. so it is more suitable to deal with occasions that other flocculants cannot treat. comparing with cationic polyacrylamide (cpam) and anionic polya-

preparation of novel amphoteric polyacrylamide and its,moreover, amphoteric polyacrylamide has the advantage of being suitable for a wide range of ph values (1,2).the surface of the paper pulp ﬁber is usually negatively charged and easy to adsorb the heterocations in the system, thus reducing the adsorption with the cation retention aid. in contrast, amphoteric polypropylene

Can cationic polyacrylamides be used in water treatment?
This applies to both the anionic and non-ionic polyacrylamides, but residual levels from cationic polyacrylamides may be higher. Acrylamide was detected at levels of 5 μg/l in both river water and tap water in an area where polyacrylamides were used in the treatment of potable water.
What are acrylamide and polyacrylamide used for?
Both acrylamide and polyacrylamide are used mainly in the production of flocculants for the clarification of potable water and in the treatment of municipal and industrial effluents. They are also used as grouting agents in the construction of drinking-water reservoirs and wells (IPCS, 1985).
How much Acrylamide is in water?
Acrylamide was detected at levels of 5 μg/l in both river water and tap water in an area where polyacrylamides were used in the treatment of potable water. Samples from public drinking-water supply wells in West Virginia in the United States of America (USA) contained 0.024–0.041 μg of acrylamide per litre.
What is polyacrylamide (PAM) used for?
High molecular weight polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction reducer in enhanced oil recovery and high-volume hydraulic fracturing.
