Abstract
The ultrasound-assisted solvent-exchange technique for aqueous fullerene dispersions (AFD) of C-60 (10(-4) - 10(-6) M) have been improved for high-yield synthesis, thereby achieving AFDs with total recovery over 90 %. Using ICP-AES, HPLC-UV, HGC-MS, the elemental and residual organic compounds have been estimated as not exceeding 3 ppm. The possible structure of fullerene clusters in AFD was assumed as {n{[}C-60]mC(6)H(5)COO(-) (m - x)Na+}xNa(+).
