Acute and long-term effects of anionic polyacrylamide (APAM) on

The application of synthetic polymers such as anionic polyacrylamides (APAM) in enhanced oil recovery (EOR) may increase in the future. This can lead to environmental release through offshore produced water discharges with so far limited knowledge on impacts in marine ecosystems. We investigated impacts of APAM polymers on two marine copepod

Fabricating an anionic polyacrylamide (APAM) with an anionic block

anionic polyacrylamide with high occulation performance have been developed and applied in the waste water treat-ment.16,17 However, the defect of the APAM, namely, the disor-dered and random distribution of anionic units in the polymer chain, seriously restricts the further enhancement of the solid-water separation ability.

Chemical cleaning of ultrafiltration membranes for polymer-flooding

Haijun Yang c Add to Mendeley https://doi.org/10.1016/j.memsci.2017.08.062 Get rights and content Abstract In a polymer-flooding wastewater treatment process, physically irreversible fouling of ultrafiltration (UF) membranes is severe and inevitable. Particularly, anionic polyacrylamide (APAM) aggravated flux loss is a challenge in flux recovery.

molecular mechanisms of ultrafiltration membrane fouling in polymer

Molecular Mechanisms of Ultrafiltration Membrane Fouling in Polymer

Polymer (i.e., anionic polyacrylamide (APAM)) fouling of polyvinylidene fluoride (PVDF) ultrafiltration (UF) membranes and its relationships to intermolecular interactions were investigated using atomic force microscopy (AFM). Distinct relations were obtained between the AFM force spectroscopy measurements and calculated fouling resistance over the concentration polarization layer (CPL) and

Adsorption of Different Ionic Types of Polyacrylamide on

The results of the QCM-D analysis showed that a decrease in pH led to an increase in the adsorption of montmorillonite on the alumina surface. The ranking of adsorption mass on alumina and pre-adsorbed montmorillonite alumina surfaces was found to be cationic polyacrylamide (CPAM) > polyacrylamide (NPAM) > anionic polyacrylamide (APAM).

Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure. In the template copolymerization system, acrylamide (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium chloride) (PAAC) as a template. The chemical properties of the polymers were observed by
