Summary:PROBLEM TO BE SOLVED: To increase the selectivity of a target material to be processed and a coexistence material and attain an efficient usage of an adsorbent when radioactive waste liquid is processed with the adsorbent.SOLUTION: Radioactive waste liquid 1 containing a target material to be processed and a coexistence material includes: a complexing agent addition mechanism for adding a complexing agent 2 and an adsorption unit 14 containing an adsorbent. The complexing agent has a smaller complex stability constant with the target material than a complex stability constant with the coexistence material.SELECTED DRAWING: Figure 1 【課題】放射性廃液を吸着剤で処理する場合において、処理対象である目的物質と共存物質との選択性を向上し、吸着剤の有効利用を図る処理装置を提供する。【解決手段】目的物質と共存物質とを含む放射性廃液１に錯化剤２を添加する錯化剤添加機構と、吸着剤を内蔵する吸着ユニット１４とを備える。錯化剤は、目的物質との錯安定定数が共存物質との錯安定定数に比べて小さい。【選択図】図１
