An Optimization Study of Polyacrylamide-Polyethylenimine-Based Polymer Gel for High Temperature Reservoir Conformance Control - Hindawi
Central composite design (CCD) was used to determine the optimized organically crosslinked polymer gel formulation. Concentrations of two main raw materials, namely, polyacrylamide (PAM) and polyethylenimine (PEI), were varied in a suitable
Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is
Synthesis and Characterization of Hydrophobically Modified Cationic Acrylamide Copolymer
A series of hydrophobic cationic monomers were introduced into acrylamide chain to form hydrophobically modified cationic polyacrylamide. The hydrophobic cationic monomer used in this study was 3
These two steps of the adsorption are accompanied by the strong shrinking of the gel composite. At high concentrations of the surfactant, total overcharging of the surface of the clay particles occurs, resulting in a change in the direction of

- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
- Do polyaluminium chloride and anionic polyacrylamide water treatment residuals adsorb phosphorus?
- Polyaluminium chloride and anionic polyacrylamide water treatment residuals (PAC-APAM WTRs) as an amendment in three types of soils with the ratios (w/w) of 10%, 15%, and 20% were evaluated for phosphorus adsorption from aqueous solutions by batch studies.
- Which compound is used to treat sewage with cationic charged particles?
- Anionic polyacrylamide (APAM), synthesized with anionic monomer and acrylamide (AM), is a macromolecular compound. It is applied to treat sewage with cationic charged particles because its anionic chemical groups have efficient charge neutralization ability and colloids destabilization ability , .
- Can anionic polyacrylamide be used in water treatment?
- What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.
