 note = {We have developed a new method for producing 191Pt from an iridium target. Alkali fusion of iridium was successfully performed using a vertical beam irradiation method and a mixed target of Ir and Na2O2, which resulted in easy dissolution of the irradiated iridium target. A trace amount of PtⅣCl62- was isolated from bulk IrⅣCl62- by solvent extraction and anion exchange chromatography. The production yield of 191Pt 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 PtⅣCl62-, and 95% for PtⅡCl42-, respectively.},
