Design anion regulated layered double hydroxide and explore its theoretical mechanism of immobilizing uranium

Adsorption-photoreduction behaviors and mechanisms of layered double hydroxide loaded on uranium(vi) removal

“…Tu et al 19 found that ternary MgAlFe-LDHs had a better removal effect of U( vi ) as compared to binary MgAl-LDHs. Cheng et al 20 systematically studied the effects of intercalation anions (CO 3 2− , PO 4 3− and SO 4 2− ) on the U( vi ) removal performance of MgAl-LDHs, and MgAl-LDHs adjusted by CO 3 2− were the most effective for U( vi ) purification. The exploration of the properties of LDH materials could have broad prospects for the application of U( vi ) decontamination.…”

“…Tu et al 19 found that ternary MgAlFe-LDHs had a better removal effect of U(VI) as compared to binary MgAl-LDHs. Cheng et al 20 The metal octahedra in LDHs are interconnected by metaloxygen-metal oxo-bridging linkages and serve as visible-lightinduced photocatalytic redox centers, which refer to the transfer of excited electrons from one metal to another. The interlayer space in LDHs plays a key role in enhancing the photocatalytic activities, which is conducive to the participation of photogenerated charge carriers in the reaction and inhibition of charge recombination.…”
