Investigation of the adsorption performance and mechanism of 2-mercaptoethane sulfonic acid intercalated modified layered double hydroxide on heavy metal ions

Unveiling glutamic acid-functionalized LDHs: understanding the Cr(vi) removal mechanism from microscopic and macroscopic view points

“…The adsorption mechanism of NiFe-LDH and glutamate-modified NiFe-LDH were investigated using the pseudo-first-order and pseudo-second-order kinetic models. 15 The linear expressions of these models wereln( Q e − Q t ) = ln Q e − k 1 t where k 1 and k 2 are the rate constants of the pseudo-first-order and pseudo-second-order kinetic models, respectively. 51 The calculations result of the kinetic constant (Table 2) indicates that the adsorption of CrO 4 2− on NiFe-LDH and Glu@NiFe-LDH was more consistent with the pseudo-second-order kinetic model.…”

“…13,14 In our previous work, we reported the use of different anion intercalation layers to achieve functionalization of LDH and to achieve selective and efficient adsorption of target pollutants. 15 Li et al 16 synthesized a chitosan-assisted EDTA intercalated LDH composite adsorbent material using an ion exchange/chemical cross-linking method and achieved efficient adsorption of Cu 2+ . Wang et al 17 designed, synthesized, and used an efficient LDH-based solid a School of Chemistry and Chemical Engineering, Nanjing University of Science and hydrogen peroxide as an oxidant/sorbent for the treatment of arsenic (As(III)) in wastewater.…”

Recent Advances in Pristine Iron Triad Metal–Organic Framework Cathodes for Alkali Metal‐Ion Batteries

“…Moreover, the π‐conjugated organic ligands could give the π‐d Ni‐MOFs some unique electronic properties, such as conductivity and optical properties. Various π‐d Ni‐MOFs, such as Ni 3 (HITP) 2 , [ 174 ] Ni‐HAB, [ 175 ] Ni[C 6 H 2 (NH) 2 ] n /Ni[C 6 H 2 (NH) 2 S 2 ] n , [ 152 ] Ni–HHTP, [ 176 ] NiTIB, [ 177 ] have been widely employed in gas separation, [ 178 ] catalysis, [ 179 ] sensing, [ 180 ] drug delivery, [ 181 ] and electrochemical applications, [ 182,183 ] especially in alkali metal‐ion batteries based on their advantages of flexibility, design versatility, conducive, and unique π‐conjugated structure.
