Impact of anionic polyacrylamide on stability and surface

The stability mechanism and thermal properties of the system alumina–anionic polyacrylamide (PAM) was studied. The polymer’s adsorption properties in dependence on the following parameters solution pH (in the range 3–9), temperature (in the range 15–35 °C), and carboxyl groups’ content in the PAM chains (in the range 5–30 %) were examined.

Quantitative characterization of polyacrylamide–shale

The anionic polyacrylamide concentration was 0.1–0.2 wt%, such that the concentration is well above C* (critical overlap concentration) and below C** (critical entanglement concentration). The concentration of shale was kept constant at 0.5 lb/bbl, and the concentration of anionic polyacrylamide was varied from 0.1 to 0.2 wt%.

Dispersion polymerization of anionic polyacrylamide in an

Anionic polyacrylamide dispersions were prepared by dispersion polymerization in an aqueous salt medium, using acrylamide(AM) and acrylic acid(AA) as monomers and anionic polyelectrolytes as stabilizer. Effects of salt concentration, and molecular weight and concentration of stabilizers on the stability of the dispersions were investigated using a HAAKE rheometer and optical microscopy.

Impact of anionic polyacrylamide on SpringerLink. The polyacrylamide-adsorbed amount increase with the rise of carboxyl group content is also observed. More numerous anionic groups cause more expanded conformation of polymeric chains. Such structure of adsorbing macromolecules favors their higher adsorption in the alumina–polymer solution system.

Effects of nonionic surfactant and associative thickener

The dilute polyacrylamide solution became highly elastic in the presence of either the nonionic surfactant on the associative thickener. A threestage model was proposed to describe the surfactant/thickener/polymer interactions.

depressing effect of hydroxamic polyacrylamide on pyrite

Depressing effect of hydroxamic polyacrylamide on pyrite

The performance of hydroxamic polyacrylamide (HPAM) in mineral flotation was tested on the samples of calcite, diaspore and pyrite. It is found that HPAM expresses intensive depression on pyrite and can be used as effective depressants for pyrite. The depression mechanism of HPAM to pyrite was investigated by the determination of contact angle, zeta potential, adsorptive capacity for

Control of Rainfall-Induced Soil Erosion with Various

Several types of organic polymers with various molecular weights and surface charges are produced for various industrial and agricultural purposes, and recent studies have shown that high molecular weight anionic polymers are the most effective in reducing runoff and soil loss. However, anionic polyacrylamide (PAM) is marketed under various commercial names with variable molecular weight and
