      abstract     = {The adsorption of anionic surfactants (sodium dodecyl
                      sulfate (SDS) and sodium bis[2-ethylhexil]sulfosuccinate
                      (AOT)) on hydrotalcite (HT) and the adsorption of
                      2,4-dichlorophenol (DCP) on HT and its modified forms from
                      aqueous solutions was studied. The modification was carried
                      out by calcinations (heat treatment) and hydrophobization
                      using different anionic surfactants. The anionic surfactant
                      isotherms were of the H-type. It was assumed that first the
                      ion exchange mechanism takes place until approximately the
                      anion exchange capacity of HT is reached and hereafter, the
                      hydrophobic mechanism occurs forming surfactant bilayers.
                      While the DCP adsorption was very poor on HT, significant
                      uptake of DCP took place on calcined HT which was attributed
                      to the simultaneously occurring rehydration and adsorption
                      during the reconstruction of the layered structure. On
                      anionic surfactant-HT complexes ("organo-hydrotalcites") DCP
                      was considerably adsolubilized in the anionic surfactant
                      layers intercalated in HT. The AOT-HT complex appeared the
                      more effective adsorbents for DCP. (C) 2003 Elsevier B.V.
