Abstract :

The sorption of hydrophobic organic contaminants such as triclocarban (TCC), in aqueous solutions and in natural waters on carbon nanomaterials was studied. In the synthetic aqueous solutions, humic acid (HA) as model natural organic matter, triclocarban (TCC), as a hydrophobic organic contaminant and fullerene C60 (weathered by mimicking environmental conditions) were used. The natural waters were completely characterized before the sorption experiments. The effects of ionic strength, concentration of organic matter and of the pH over the adsorption of TCC on the carbon nanomaterial selected in these experiments, C60 were studied. A model for the adsorption mechanism, as well as an attempt to mimic the real environmental samples with characteristics alike to the optimum ones found in the synthetic samples was developed.
