Polyacrylamide Soil Conditioners: The Impact on Nanostructured Clay Minerals¡¯ Aggregation and Heavy Metals¡¯ Circulation in the Soil

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.

Chapter 8 POLYACRYLAMIDES WE1 S. YEN, ANTHONY T. COSCIA and SAMUEL I. KOHEN INTRODUCTION Among the various polymers that have been studied for chemical enhanced oil recovery (see Chapter 7), polyacrylamide (PAM) is the most important. PAM is used frequently for mobility control as well as permeability control.

Molecular Dynamics-Assisted Design of High Temperature-Resistant Polyacrylamide/Poloxamer Interpenetrating Network Hydrogels - MDPI

Polyacrylamide has promising applications in a wide variety of fields. However, conventional polyacrylamide is prone to hydrolysis and thermal degradation under high temperature conditions, resulting in a decrease in solution viscosity with increasing temperature, which limits its practical effect. Herein, combining molecular dynamics and practical experiments, we explored a facile and fast

Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes - Springer

Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown
