Selenite is an inorganic pollutant in groundwater, affecting human health. cLDHs with increased porosity and mesoporous structure, exhibit the excellent selenite removal performance. High affinity and adsorption capacity of cLDHs were performed, and the maximum adsorption capacity of selenite was 179.59 mg/g. Pseudo-second-order and Langmuir models well described kinetic and isotherm data. The adsorbent could be used circularly 4 times efficiently. Final removal of selenite ions is by reassembling and reconstructing to hydrotalcites structures.
