acute and long-term effects of anionic polyacrylamide (apam,their chemical composition and ionic character depend on the functional groups added to the acrylamide chemical moiety (abidin et al., 2012; acharya et al., 2010). they can occur in non-ionic form, or as polyelectrolytes in cationic (cpam) and anionic (apam) form and are produced in various molecular weights depending on their intended application.

binding of anionic polyacrylamide with amidase and laccase

amidase and laccase play a key role in the degradation process of anionic polyacrylamide (hpam). however, the largest challenge of hpam enzymatic degradation is whether the enzyme can bind with a substrate for a period of time. here, the most suitable complexes, namely, rh amidase-hpam-2 and bacillus subtilis (b. subtilis) laccase-hpam-3, were obtained by docking, and they were carried out for

sand washing machine jxsc machinery mineral processing.the motor-driven impeller rotates slowly after the v-belt, reducer, and gear reduce speed. the sand enters the washing tank from the feed tank and rolls under the drive of the impeller, grinding away the impurities covering the surface of the sand and gravel, and at the same time destroying the water vapor layer covered by the sand particles to facilitate dehydration.

polyelectrolyte polymers—types, forms, and function

the polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. the anionic polyacrylamide in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (phpa), although they are in actuality copolymers [80]. both

pam (anionic polyacrylamide) industrial chemical products,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.

Does high mw anionic Pam outperform cationic polymers?
The use of high MW anionic PAM in the flocculation of negatively charged particles outperforms cationic polymers by enhancing the settling rate and establishing a distinct sediment shape . Only minimal adsorption is possible due to electrostatic repulsion between kaolinite particles (which have a negative charge) and the polymer.
Is cationic Pam effective in flocculation?
The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers. Non-ionic PAM was shown to be ineffective at flocculating tailing particles. The ionicity of the polymer appears to be highly relevant here, based on the results.
Are cationic polyacrylamides better than anionic polyamides?
They suggested that cationic polyacrylamides (PAM) produced floc aggregates with larger size, greater shear-resistant ability and higher regrowth capacity than anionic one, arising from the contribution of charge neutralization and bridging effects , , .
How strong is a cationic Pam compared to a nonionic Pam?
Besides, the average of maturated floc strength factor for cationic PAM (77 %) was somewhat greater than that for either anionic or nonionic PAMs (both ≈ 69 %).
