A review on the influence of chemical modification on the

Adsorbents are insoluble porous solids capable of binding liquid or gaseous molecules to their surfaces in a simple and cost-effective method of water treatment. The performance of an adsorbent depends on the chemical and physical properties of the adsorbent surface as well as that of the soluble substances. The chemical modification provides a

The effects of chemical modification on adsorbent performance

The adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface is known as adsorption (Amalina et al., 2022a; Ge et al., 2021).The adsorbate is the substance that is adsorbed, and the adsorbent is a solid on which the substance accumulates (Abdulrahman et al., 2020).

Polyelectrolyte polymers¡ªTypes, 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 polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers [80] .

Water-based polymer drilling fluid and method of use

Abstract. A water-based drilling fluid comprises a polymer which is a non-ionic polymer or an anionic polymer. The polymer can be a polyacrylamide. The fluid is used for drilling subterranean formations containing heavy crude oil and bitumen-rich oil sands, and may comprise additional fluid components.

(PDF) Quantitative characterization of polyacrylamide¨Cshale interaction

the anionic polyacrylamide was used to rheologically. … This work presents a comprehensive review on the use of bio-inhibitors for stabilizing gas/oil shales during drilling and hydraulic …


Synonyms: Anionic polyacrylamide 3 PHYSICO-CHEMICAL PROPERTIES Polyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polymerisation of acrylamide. Anionic polyacrylamide polymer can then be formed from the hydrolysis of the
