Polyacrylamide comes in various forms, including anionic, cationic, and nonionic variants, each catering to different functionalities. The anionic form, for instance, has a negative charge and is often used for flocculation processes in water treatment. Conversely, the cationic form carries a positive charge and is utilized in applications requiring coagulation or retention.
Lastly, with the increasing emphasis on sustainable chemistry, EDF shows potential as a biodegradable alternative to petroleum-based solvents. Its origin from renewable resources positions it favorably in the context of green chemistry initiatives.
