Abstract

A novel Fe/Co metal organic complex nanosheet modified by 1,4-dicarboxybenzene (BDC), i.e., FeCo@BDC, was prepared, and highly efficient removal performance for trace lead (II) (Pb²⁺) was demonstrated in the neutral aqueous solutions. The removal rates were higher than 95% and the adsorption was equilibrated in 15 min. The isotherms and kinetics for the adsorption Pb²⁺ by the FeCo@BDC adsorbents followed Langmuir model and pseudo-second-order model, respectively. The maximum adsorption capacity was 220.48 mg•g⁻¹. The FeCo@BDC adsorbents also own a prominent regeneration performance. The prominent performance of in the removal of trace Pb²⁺ makes FeCo@BDC an ideal candidate as commercial adsorbent materials.
