摘要
The absorption behavior of68Ga(III) and68Ge(IV) on three different type of ferric oxides has been studied. Alpha-ferric oxide in trigonal structure is found to be a suitable material for the generator. The elution yield of68Ga from the column of trigonal crystal of α-ferric oxide with absorbed68Ge(IV) can reach 90% in 1 ml 0.05 mol/l HCl solution, while the breakthrough of68Ge was less than 1.8·10−4. This generator is stable and resistant to chemicals and radiation. The content of Fe in 1 ml eluate is less than 0.1 ppm. The recovery of68Ga was higher and more constant than that of the known68Ge−68Ga generator system.
