Abstract

Addressing soil pollution by metals and metalloids necessitates innovative and efficient adsorbent materials. This study scrutinizes layered double hydroxides (LDHs) for their structural versatility and enhanced adsorption capabilities, pivotal in soil remediation. The paper systematically explores the structural characteristics, synthesis methods, and modification techniques of LDHs, as well as their interaction mechanisms with diverse metal(loid) species, such as anionic forms (e.g., AsO 4 3− ) and oxygenated ions (e.g., CrO 4 2− , MnO 4 − ). It presents a methodical review of the current understanding and progress in soil treatment strategies, emphasizing the application potential of LDHs. This comprehensive analysis not only underscores the efficacy of LDHs in decontaminating soils but also lays the groundwork for future research trajectories in environmental remediation technologies.
