Insights into Adsorption Behavior and Mechanism of Br– onto Nickel–Aluminum Layered Double Hydroxides Intercalated with Different Inorganic Anions

Layered double hydroxides (LDHs) have garnered significant attention from researchers in the field of adsorption due to their unique laminated structures and ion exchange properties. LDHs with various anion intercalation showed different adsorption effects on adsorbing ions, but the corresponding adsorption mechanisms are ambiguous. In this study, three types of NiAl-LDHs were synthesized, utilizing NO
