Molecular Dynamics Simulation of Polyacrylamide Adsorption on

An adsorption-free energy analysis, using an enhanced umbrella sampling method, is applied to evaluate the chemical adsorption performance. The interaction energy analysis shows that the polyacrylamide-based polymers display favourable interactions with the calcite structure.

Flocculation performance and mechanism of P (DMDAAC-AM) on

Experimental results reveal that PDA exerts a better flocculation and sedimentation effect than the commercially polyacrylamide (PAM) on kaolinite and montmorillonite suspensions, and the effect exerted by PDA on the kaolinite suspension is stronger than that on montmorillonite.

Adsorption of Hydrolysed Polyacrylamide onto Calcium

Abstract. Carbonate rock strengthening using chemical techniques is a strategy to prevent excessive fines migration during oil and gas production. We provide herein a study of the adsorption of three types of hydrolysed polyacrylamide (HPAM) of different molecular weight (F3330S, 11¨C13 MDa; F3530 S, 15¨C17 MDa; F3630S, 18¨C20 MDa) onto

Enhance the mechanical performance of polyacrylamide hydrogel

Polyacrylamide (PAM)¨Csilica nanocomposite hydrogels with enhanced mechanical performance were synthesized by in situ polymerization of acrylamide in the presence of colloidal silica nanoparticles. Two kinds of silica particle dispersions with different surface properties, CAL25 and 30R25, were used as models.

Removal of Methylene Blue from Wastewater Using a Ternary

Then, the adsorption performance of PUL/PAM/GO hydrogel for MB was researched, including the dose, temperature, contact time, pH, adsorption isotherm, adsorption kinetics, and adsorption thermodynamics and swelling properties. The effects of various salts in real wastewater on adsorption were simulated.

Interaction between PAM and kaolinite (0 0 1) surface in

Analysis of the dynamic properties of water indicated that the effect of polyacrylamide adsorption on the wettability of the kaolinite (0 0 1) surface showed identical trends as adsorption strength. The simulation results are in good agreement with the experimental data. Graphical abstract Download : Download high-res image (417KB)
