Abstract
Because of their broad applications, fullerenes(C60)have raised concerns over the environmental safety. In this study, interactions of fullerene with environmental materials(carbon nanotubes and inorganic minerals)were examined in batch adsorption experiments. Sol-vent exchange method was used to produce fullerene colloidal suspensions. Three types of multi-walled carbon nanotubes:hydroxylation of multi-walled carbon nanotubes(MH), carboxylated multi-walled carbon nanotubes(MC), and graphitized carbon nanotubes(MG)and five types of inorganic minerals:silica(SiO2), montmorillonite K10(ML-K10), montmorillonite KSF(ML-KSF), kaolin 325(KL-325)and kaolin 6000(KL-6000)were chosen. Isotherms of fullerene on carbon nanotubes and inorganic minerals could be described better by Fre-undlich than by Langmuir models. Of carbon nanotubes, MG had the highest single-point adsorption capacity(Kd)and the strongest adsorp-tion of fullerene because of the electrostatic and hydrophobic interaction. Among inorganic minerals, ML-KSF showed the greatest single-point capacity and intensity of adsorption, probably due to the presence of hydrophobic oxygen atom interlayer and positive and negative charges on the edges. Fullerene adsorption on kaolin(KL-6000 and KL-325)was closely related with the surface area.关键词
