106番元素シーボーギウム(Sg)の抽出クロマトグラフ実験に向け、HCl溶液からAliquat336担持樹脂へのMoとWの無担体放射性トレーサーの固液抽出挙動を調べた。HCl濃度変化に対するMoとWの分配係数($${it K}$$$$_{d}$$)の変化をバッチ法により測定した。また迅速自動分離装置を用いたMoとWのオンライン抽出クロマトグラフィー実験も2-8M HCl溶液を用いて行った。2-8M HCl溶液中における抽出率はMo$$>$$Wとなり、バッチ法で得た$${it K}$$$$_{d}$$の順列を反映する結果が得られた。

We studied solid-liquid extraction behavior of carrier-free Mo and W radiotracers onto an Aliquat 336-loaded resin from HCl solutions toward extraction chromatography experiments of element 106, seaborgium(Sg). Distribution coefficients ($${it K}$$$$_{d}$$) of Mo and W on the resin were determined as a function of HCl concentration by a batch method. On-line extraction chromatography of Mo and W was also carried out in 2-8 M HCl solutions with an automated rapid chemistry apparatus. The order of extraction probability from 2 to 8 M HCl was Mo$$>$$W, which reflected the order of the $${it K}$$$$_{d}$$ values in the batch experiment.
