| Abstract: | A series of calcium aluminum layered double hydroxides (LDHs) modified with sodium dodecyl sulfate (SDS) (Ca/Al-SDS-LDHs) were synthesized by co-precipitation, and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and elemental analysis. The Ca/Al-SDS-LDHs enhanced sorption of nitrobenzene and naphthalene from water compared with inor- ganic LDH (Ca/Al-Cl-LDH). The sorption isotherms for sorption of organic contaminants onto the Ca/Al-SDS-LDHs were linear for the concentration ran... |
