Abstract

The use of modified clays for environmental remediation is heavily investigated Different organic compounds containing fluorine are contaminating the environment and damage human health as well can form complexes with other compounds 1 Modified clays can be efficient for the removal of ionic and non ionic contaminants. New bioinspired materials are being developed continuously in order to answer the environmental challenges that nature suffer as a consequence of human activities while water utilities keep optimizing processes and cost and using new technology developed elsewhere. Micelle clay composites have been used for environmental remediation and for the removal of organic pollutants from water. The removal of fluorinated compounds from water and soil is difficult Fluorocarbons can form self assembled structures and membranes that are at the same time hydrophobic and lipophobic. In this research we investigate the use of hybrid catanionic fluoro hydrocarbon surfactants, known to form membranous vesicular structures to combine with clays to prepare fluoro vesicles clay composites for the removal of fluoro compounds from water.
