The preparation of no-carrier-added48V(IV) and48V(V) from a natural titanium target irradiated by a proton beam has been developed. The48V recovered from the target by solvent extraction was purified as48V(V) with a cation exchange column and then converted to48V(IV) by reduction with ethanol. One hour irradiations at 10 μA of 18 MeV protons gave approximately 2mCi (a radiochemical yield of 41%) of radiochemically pure and almost salt-free48V(IV) and48V(V) with high specific activities. They were shown to be suitable for biological tracer use.
