Biodegradation of Polyacrylamide and Its Derivatives

Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 ¡Á 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).

using polyacrylamide (pam) to reduce erosion on construction sites

Using Polyacrylamide (PAM) to Reduce Erosion on Construction Sites

PAM is a term describing a wide variety of chemicals based on the acrylamide and acrylate units. When linked in long chains, these units can be modified to result in a net positive, neutral, or negative charge on the PAM molecule. The positively charged, or cationic, PAMs, are not used for erosion control because they can be toxic to fish and

Linear polyacrylamide will affect polymerization, since it serves as a nucleus for polymerization. The most important effect is the loss of reproducibility in gel porosity and relative mobilities of proteins and nucleic acids. Linear polyacrylamide is detected as water or alcohol insolubles and should be

Optimizing the Flocculation Effect of Cationic Polyacrylamide ... - MDPI

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM. In this paper, the optimal flocculation conditions of a novel CPAM were
