| Research Abstract |
In this study, the removal ability for dilute organic compounds was investigated for the anionic surfactant-supported layered double hydroxide (LDH), which is synthesized from aluminum dross. Concretely, the adsorption behavior of dodecyl sulfate ions (DS-), dodecyl benzene sulfonate ions (DBS-) and Octane sulfonate ions (OS-) were researched using the LDH. The effect of ion size and adsorption amount of anionic surfactants on the interlayer distance and contact angle of LDH were considered from a series of experimental data. The removal ability of the LDHs was clarified for 6 kinds of organic compounds.
