Reaction of Hydroxyfullerene with Metal Salts:A Route to Remediation and Immobilization

摘要

There has recently been much publicity given to both the potential toxicity1 and physiological benefit of fullerenes and their derivatives.With regard to toxicity,interest has focused on the water-soluble aggregate n-C_(60),formed by either the partial hydrolysis of C_(60) or the water extraction of a C_(60)-solvent clathrate from organic solvents.Studies with human skin (HDF) and liver carcinoma (HepG2) cells and large mouth bass have indicated potential concerns that n-C_(60) shows a high toxicity.In contrast,hydroxy-fullerenes [fullerenol,"C_(60)(OH)_n"] were shown to have negligible toxicity.
