|
Water is the most prevalent liquid on Earth; nonetheless, just 2.5% of the global water supply is freshwater. Currently, initiatives to desalinate saltwater and brackish water for potable water production are crucial. Recently, a novel substance known as hydrogel has garnered interest in desalination procedures. Innovative uses of hydrogels have been suggested for forward osmosis desalination, solar desalination, electrodialysis, and capacitive desalination. Cost-effective and straightforward desalination techniques are essential for the generation of potable water. Hydrogel formulations are among the foremost alternatives in this domain. Hydrogels are categorized according to their physical structure, ionic charge, production techniques, particle size, chemical and physical bonding, and mechanical qualities. This research encapsulates current advancements in hydrogels and their prospective use in desalination and purified water production.
