Transfer and degradation of polyacrylamide-based flocculants
This review focuses on the fate of PAM-based flocculants in hydrosystems, with a major emphasis on the mechanisms of transfer and degradation, which can affect both PAM and associated AMD. The section dedicated to transfer phenomenon will especially examine transport and reactivity with solid matrices.
Chemical Degradation of Polyacrylamide during Hydraulic
Polyacrylamide (PAM) based friction reducers are a primary ingredient of slickwater hydraulic fracturing fluids. Little is known regarding the fate of these polymers under downhole conditions, which could have important environmental impacts including decisions on strategies for reuse or treatment of flowback water. The objective of this study was to evaluate the chemical degradation of high,Polymers | Free Full-Text | Optimizing Salt Leakage In this research, we prepared a polyacrylamide hydrogel through free radical polymerization, and its water-absorbing capabilities were improved by incorporating the hygroscopic salt lithium chloride. We compared it to a salt-based porous adsorbent, AlFum-LiCl, which also exhibited strong water adsorption properties and the potential for large

Binding of Anionic Polyacrylamide with Amidase and Laccase
Amidase and laccase play a key role in the degradation process of anionic polyacrylamide (HPAM). However, the largest challenge of HPAM enzymatic degradation is whether the enzyme can bind with a substrate for a period of time. Here, the most suitable complexes, namely, Rh Amidase-HPAM-2 and Bacillus subtilis (B. subtilis) laccase-HPAM-3, were obtained by docking, and they were carried out for,Effects of Anionic Asphalt Emulsion on Early-Age Cement 3.1 Influence of Anionic Asphalt Emulsion on Cement Set Time. Figure 16.1 shows that both the initial and the final set times were prolonged with the increase of the A/C from 0 to 0.32, which implies that the PC hydration was retarded by the anionic asphalt emulsion.

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 acrylamide homopolymer either simultaneously during the polymerisation process or as a subsequent step (Zheng et al., 2013).,poly aluminium chloride industrial grade supplier Water Treatment Chemical Industrial Grade Coagulant 28%-30% Poly Aluminum Chloride PAC
