英文摘要: Abstract(#br)We have developed a new method for producing 191 Pt from an iridium target. Alkali fusion of iridium was successfully performed using a vertical beam irradiation method and a mixed target of Ir and Na 2 O 2 , which resulted in easy dissolution of the irradiated iridium target. A trace amount of Pt Ⅳ Cl 6 2- was isolated from bulk Ir Ⅳ Cl 6 2- by solvent extraction and anion exchange chromatography. The production yield of 191 Pt was 7.1 ± 0.4 (MBq/μA h, EOB) by proton irradiation at 30 MeV. The radioplatinum product (n.c.a.) was prepared at a radiochemical purity of 97% for Pt Ⅳ Cl 6 2- , and 95% for Pt Ⅱ Cl 4 2- , respectively.
