英文摘要：

Work presented here evaluated adsorption of aqueous aggregates of C60 fullerene nanoparticles （. nC60 ） on artificial biological membranes under different influencing factors. The results show that the artificial biological membranes can adsorb nC60 and the adsorption capacity of nC60 was impacted by initial nC60 concentrations, pH, and amount of adsorbent. Both Henry linear partition model and Freundlich model were used for data fitting of the sorption isotherms of nC60. The adsorption capacity of nC60 increased with increasing initial nC60 concentration. When the initial nC60 concentration increased from 1.0 mg＂ L- 1 to 11.6 rag＂ L- 1, the adsorption capacity of nC60 increased from 111.9 mg＇kg-~ to 813.2 mg＇kg-1. The adsorption capacity of nC60 were also pH-dependent with the accumulation of nC60 onto artificial biological membranes increasing systematically as the pH decreased from 8 （ natural water pH） to 3 （ the low end of physiologically relevant pH）, and its maximum value increased from 258.4 mg. kg^-1 to 742.0 mg. kg^-1. When the initial nC60 concentration was designed at 5.2 mg.L^-1,it was found that artificial biological membranes of 0.3 g had the optimal adsorption for nC60.
