HPLC Elution Behavior of La-Fullerenes Investigated by Radiochemical Method

Abstract
HPLC elution behaviors of La-fullerenes were investigated by use of the radiochemical methods. Elution curves of La-fullerenes could be observed in detail for the first time, and the persistent presence of La in the whole elution curve was demonstrated. Production of La-fullerenes containing a radioactive 140La could be achieved for the first time.
