A new HPLC stationary phase, l-methylnaphthalene modified Polystyrene-divin
ylbenzene resin (MNPSDVB), has been prepared to separate C-60 and C-70. Hig
h column loading capacity and large separation factor of C-60 and C-70 were
obtained in MNPSDVB column with the strong solvent, o-xylene, as the mobil
e phase.
