Polyelectrolyte polymers¡ªTypes, forms, and function

34.1. Synthetic polyelectrolytes There are many definitions for polymeric polyelectrolytes in the literature [1], [2], [3]. In the simplest sense, water-soluble polyelectrolytes are polymers that contain charged disassociating monomer subunits. The charges can be pendant to the polymer chain or be part of the polymer chain itself.

Sustainability | Free Full-Text | Effectively Recycling Swine Wastewater by Coagulation–Flocculation of Nonionic Polyacrylamide

Recycling swine wastewater is an environmental and economic issue for promoting the sustainable development of the pig industry worldwide. The application of a flocculant, non-ionic polyacrylamide (NPAM) for treating the contaminants in wastewater was trialed in this study. Firstly, the optimal pH value for the coagulation¨Cflocculation of NPAM was adjusted by hydrochloric acid and sodium ...

Polyacrylamide is a water-soluble synthetic polyelectrolyte which consists of repeating units (forming a chain structure and containing hydrophilic groups). Due to the different nature of the groups present in the macromolecules, polyacrylamides can be divided into nonionic, anionic, and cationic ones.

Understanding the roles and characterizing the intrinsic properties of synthetic vs. natural polymers to improve clarification through

The term flocculation as used in this review will refer to the ability of a moderate-to-very-high-MW polymer (anionic, cationic, nonionic, or amphoteric) to accelerate and improve particulate matter agglomeration ( i.e., already destabilized solids) via an interparticle bridging mechanism.

Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2022). The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2 .
