Finally C60 colloidal dispersion was produced in water with the help of high-energy sonication probe. Sorptive properties of C60 colloidal particles were also studied with naphthalene. Sorption partition coefficients could vary by orders of magnitude and have been observed to be related to the different C60 aggregation forms. Sorption/desorption hysteresis, a common phenomenon observed in natural soils and sediments, was also observed in this work with naphthalene sorbed to well dispersed C60 aggregates. Data were fitted with dual-equilibrium desorption model and results were comparable to literature reported results for natural organic carbons.115 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
