Hydrogel-based superadsorbents for efficient removal of heavy metals in industrial wastewater treatment and environmental conservation

Superadsorbent hydrogels have become a viable solution to the urgent problem of industrial wastewater contamination. This paper offers a thorough analysis of the most recent advancements in superadsorbent hydrogels, highlighting their potential to reduce pollution from industrial waste and support environmental preservation. The review begins with an explanation of the basic properties and principles of superadsorbent hydrogels, with a focus on their exceptional ability to swell with water. The story then flows into a thorough analysis of wastewater treatment, explaining how superadsorbent hydrogels interact with pollutants. Synthesis processes using natural, synthetic, and hybrid materials are examined to reveal the many strategies used to produce these hydrogels. In addition, the study explores the environmental effects of using superadsorbent hydrogels in wastewater treatment, assessing possible effects on soil and aquatic environments. This research highlights the revolutionary potential of superadsorbent hydrogels in improving industrial wastewater treatment methods while also protecting the environment.
