Abstract Organic 3D flower-like layered double hydroxide (3D-SLDH) was prepared by sodium dodecyl sulfate (SDS) under various urea concentrations. X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray energy dispersive spectral analysis (EDS), and Brunauer-Emmett-Teller (BET) were employed to determine the optimum synthesis condition. The adsorption performance of 3D-SLDH for acid orange 7 (AO7), rhodamine B (RhB), and naphthalene (NAP) was studied by static adsorption experiments. The results showed that the adsorption capacity of 3D-SLDH toward AO7, RhB, and NAP could reach up to 454.9, 46.8 and 43.7mg/g, respectively, indicating that 3D-SLDH is a universal adsorbent to organic pollutants. Adsorption kinetics demonstrated that all contaminants removal could be well described by the pseudo-second-order model. The adsorption isotherms of AO7 and RhB fitted the Langmuir model, while partition-adsorption model was suitable for NAP adsorption. Moreover, the elevated temperature benefited for both AO7 and RhB adsorption. By contrast, lower temperature is suitable for NAP removal. Combined with the analysis of XRD, FT-IR, and XPS, the removal mechanism of AO7, RhB and NAP on 3D-SLDH was investigated. Ion exchange and surface adsorption contributed to AO7 and RhB adsorption, respectively. Whereas partition played a dominant role in NAP removal.
