polyacrylamide degradation and its implications in environmental

Polyacrylamide degradation and its implications in environmental

The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1, 9,...

ANIONIC POLYACRYLAMIDE - Santos

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Polyelectrolyte polymers¡ªTypes, forms, and function

Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.

Water Soluble Polymer Flocculants: Synthesis, Characterization,

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

Polyacrylamide Soil Conditioners: The Impact on

Due to the different nature of the groups present in the macromolecules, polyacrylamides can be divided into nonionic, anionic, and cationic ones. They are used in many industries, including mineral processing; wastewater treatment; production of paints, inks, varnishes, plastics, paper, cosmetics, and ceramics; pharmacy, food industry, or in agriculture as polymeric additives controlling soil

Comparison of adsorption affinity of anionic and cationic

For determination of anionic polyacrylamide concentration in the solution the reaction of polyacrylamide with hyamine proposed by Crummet and Hummel was applied. It is based on the spectrophotometric measurements of absorbance generated by the PAM reaction with hyamine 1622 ( N -benzyl- N,N -dimethyl-2-{2-[4-(2,4,4-trimethylpentan-2-yl)phenoxy]ethoxy}ethanaminiumchloride).

effects of soil and water properties on anionic polyacrylamide sorption

Effects of soil and water properties on anionic polyacrylamide Sorption

Knowing the sorptive behavior of anionic polyacrylamide (PAM) by soils is useful in predicting the appropriate application rate, depth of effective treatment, and its mobility in soils, Sorption isotherms of PAM by soil materials, six natural soils, and their subsamples with partial organic matter (OM) removed by H 2 O 2 oxidization under different dissolved salt concentrations were examined.

Comparative study of anion polyacrylamide (APAM

The adsorption of this kind of anionic polyacrylamide conformed to the Langmuir¨CFreundlich model, and the fitting R 2 values were 0.9657, 0.9720 for OM and MM, respectively. The donation rate caused by static adsorption on the membrane fouling was not very big, and the relative flux (RF) of OM and MM was about 0.89 and 0.72, respectively.
