anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

Synonyms: Anionic polyacrylamide 3 PHYSICO-CHEMICAL PROPERTIES Polyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polymerisation of acrylamide. Anionic polyacrylamide polymer can then be formed from the hydrolysis of the

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,...

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Fabricating an anionic polyacrylamide (APAM) with an anionic block

The resonance peak observed at 34.72 ppm in PAM was attributed to the backbone ¨CCH 2 ¨C (a) group. 31 The peak at 42.08 ppm in PAM was derived from the backbone ¨CCH¨C (b) group. 19 Meanwhile, except for the similar resonance peaks with PAM, the characteristic resonance peaks of the ¨CCH 2 SO 3 ¨C (d) chemical group in both TPAS and APAS were all manifested at 56.14 ppm, which further

PAM (anionic Polyacrylamide) for Runoff and Soil Erosion Control. PAM, or anionic Polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss. The chemical when applied as a liquid solution to a freshly-tilled

Polyacrylamide in Agriculture and Environmental Land Management

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation©induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms

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

Anionic polyacrylamides (aPAMs) are used in the construction field as a thickener or flocculent. Their chemical structure is shown in Figure 9.30. APAMs are synthesized by free radical polymerization of acrylamide and acrylic acid salts or by partial hydrolysis of non-ionic polyacrylamide (Cheng 2004; Bessaies-Bey et al., 2015).

Anionic polyacrylamide influence on the lead(II) ion accumulation in

Purpose Polymeric substances, as soil conditioners, limit the erosion process as well as improve the soil structure. The same macromolecular compounds may influence the heavy metal accumulation in soil environment. The main aim of this study was investigation of anionic polyacrylamide (AN PAM) effect on the lead(II) ion sorption on the montmorillonite surface. The effects of Pb(II) ion
