چکیده انگلیسی
The preparation of MgAl layer-structured double hydroxide (MgAl LDH) particles equipped with the function of an organic acid has been attempted by modifying the interlayer with dodecylsulfate ion (DSâ). MgAl LDH, which had DSâ intercalated in the interlayer, was synthesized by the dropwise addition of a solution of Mg(NO3)2 and Al(NO3)3 to an aqueous solution of sodium dodecylsulfate at a constant pH of 10.0. The DSâ-modified MgAl LDH particle was found to have an uptake capacity for bisphenol A in an aqueous solution. This indicates that the function of DSâ as an organic material was adequately maintained in the interlayer of the MgAl LDH. The uptake capacity increased with the increasing content of DSâ intercalated in the interlayer. The bisphenol A uptaken by the DSâ-intercalated MgAl LDH was confirmed to be extracted with ethanol. The DSâ-intercalated MgAl LDH treated by the ethanol had a bisphenol A uptake capacity comparable to that of fresh LDH. These results indicate that DSâ-intercalated MgAl LDH retains its activity during repeated cycles of the uptake and ethanol extraction of bisphenol A.
