Abstract
The features of the synthesis and the structure formation of homogenous phases of Mg(II),Fe(III)-layered double hydroxides with different Mg/Fe ratio in the reaction mixtures have been investigated. The effect of synthesis conditions of the materials, arrangement and molar ratio of the cations in a brucite-like layer, and polytypes of crystalline structure on the sorption properties toward ibuprofen has been studied. The sorption isotherms of ibuprofen on the synthesized sorbents at pH0 = 7,0 are satisfyingly fitted by the Langmuir model. The influence of the Mg2+/Fe3+ molar ratio and, respectively, the dimensions of the interlayer space on the maximum adsorption capacities toward ibuprofen in the aqueous solution is not observed. These results can be explained by the interaction of the adsorbate with the surface hydroxyl groups of brucite-like layers, as well as complexing reactions with structure-forming cations of the obtained sorbents.
