Abstract

Ascending paper chromatography using Toyo No. 50 paper and n-BuOH saturated with 1.0M HNO3 as a developing solvent, was useful to examine the separation of polonium species in (H,NH4)NO3 solutions. A neutral mononuclear species (Po(OH)4) appeared in the vicinity of Rf=0.6. The Rf values of each species decreased depending on the increasing cationic tendency and polymerization of the polonium species.
