Claims (2)
- 水平に配置されかつ上下方向に互いに離間して段差状に配置された複数の棚板で構成された安息角多層支持体が設置された吸着脱離塔内にて、遊離ヨウ素を含有するヨウ素イオン液のヨウ素イオンを強塩基性イオン交換樹脂で吸着する吸着脱離方法において、
安息角多層支持体より下方から吸着脱離塔内を上昇するようにヨウ素イオン液を供給し、
安息角多層支持体より上方から吸着脱離塔内を下降するように強塩基性イオン交換樹脂を供給し、
安息角多層支持体においてヨウ素イオン液と強塩基性イオン交換樹脂とを向流接触させることで、強塩基性イオン交換樹脂にてヨウ素イオン液のヨウ素イオンを吸着させ、
そのヨウ素イオンの吸着による真比重の増加にともなって強塩基性イオン交換樹脂が下降し、
ヨウ素イオン液を一旦停止後、ヨウ素イオンを吸着して真比重が増加した強塩基性イオン交換樹脂を、安息角多層支持体上からヨウ素イオン液とともに安息角多層支持体の下側へ移動させる
ことを特徴とする吸着脱離方法。 - 安息角多層支持体は、強塩基イオン交換樹脂を滞留可能な粒子滞留部と、下方からのヨウ素イオン液が流入可能な液体流入部とを有し、
各棚板は、内側縁部と下側に位置する液体流入部とを結ぶ直線の角度が強塩基性イオン交換樹脂の安息角である11°以下であり、
ヨウ素イオンを吸着して真比重が増加した強塩基性イオン交換樹脂をヨウ素イオン液とともに粒子滞留部から安息角多層支持体の下側へ移動させる
ことを特徴とする請求項1記載の吸着脱離方法。
