Dubnium-262 was produced in the $$^{248}$$Cm($$^{19}$$F, 5n) reaction at the JAEA tandem accelerator. Reaction products were rapidly transported by a He/KF gas-jet system to the chemistry laboratory. Anion-exchange behavior of Db in HF/HNO$$_{3}$$ solution was then investigated using the newly developed on-line ion-exchange and $$alpha$$-particle detection apparatus. Distribution coefficients of Db were clearly smaller than those of Ta, the closest homologue in the periodic table, and were close to those of lighter homologue Nb and also the pseudo homologue Pa. Fluoride complex formation of Db will be discussed.
