Preparation of Cu-Al layered double hydroxide intercalated with ethylenediaminetetraacetate by coprecipitation and its uptake of rare earth ions from aqueous solution

► An edta
- Cu-Al LDH was prepared by coprecipitation. ► The edta
- Cu-Al LDH was found to take up rare earth ions from aqueous solution. ► The edta ions retain their chelating function in a Cu-Al LDH interlayer.
