Determination of Polyacrylamides in Reclaimed Water Determination of Polyacrylamides in Reclaimed Water Application Note Introduction Polyacrylamides are often used as settling aids in water clarification processes. These polymers act as flocculants to help remove contaminants from the water stream.

Determination of Polyacrylamides in Reclaimed Water Greg Saunders Polymer Laboratories, now a part of Varian, Inc. Introduction Polyacrylamides are often used as settling aids in water clarification processes. These polymers act as flocculants to help remove contaminants from the water stream. Residual polyacrylamides in the reclaimed water can

Polyacrylamide degradation and its implications in - Nature

This article discusses two methods for the determination of polyacrylamides in potable water: the distillation-nesslerization method; and, the turbidimetric method. Both methods are presented in terms of apparatus, reagents, preparation of standard curve, procedure, and results.

For health concerns, use of polyacrylamides in drinking water has been subjected to closer evaluation during the last decade. Currently, dosage standards are indirectly based on the maximum concentration of acrylamide that would result from use of a commercial formulation of known acrylamide content.

The Determination of Traces of Polyacrylamides in Water - JSTOR

the determination of organic nitrogen in water has been studied in detail by Thompson and Morrison,2 who point out that the conditions for the diges- tion of organic matter depend on the nature of the material being analyzed. In the present investigation, optimum conditions for the digestion of poly- acrylamides have been determined.

Polyacrylamide - Wikipedia

[1] Copolymers and modified polymers Linear polyacrylamide is a water-soluble polymer. Other polar solvents include DMSO and various alcohols. Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels .

Polyacrylamide | chemical compound | Britannica

polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C3H5NO), a compound obtained by the hydration of acrylonitrile. Acrylamide is usually dissolved in water; it has toxic effects on the nervous system and must be handled

Synthesis and Characterization of Different Molecular Weights

suspension and related purposes. Polyacrylamides can be classified to three categories: non-ionic, anionic and cationic polyacrylamides (4). Polyacrylamides were used extensively as a flocculant in the clarification of water in industrial and municipal processes (5). Cationic polyelectrolytes are a class of polyelectrolytes that derive

Acrylamide - U.S. Environmental Protection Agency

Acrylamide occurs as a white, crystalline solid or flake-like crystals and is highly soluble in water. (2,3) Acrylamide is odorless. (2) The vapor pressure for acrylamide is 0.007 mm Hg at 25 °C, and its log octanol/water partition coefficient (log K ow) is -0.67. (2) Conversion Factors: To convert concentrations in air (at 25°C) from ppm to
