Zusammenfassung:	To provide a selenium absorber, a selenium absorber set, and a selenium removal method, which enable absorption of selenium irrespective of pH and even when other anions are included.SOLUTION: A selenium absorber comprises a polymer gel which is a copolymer of a tertiary nitrogen atom-containing monomer having a polymerizable unsaturated group and a quaternary nitrogen atom-containing monomer having a polymerizable unsaturated group. A selenium absorbent set comprises a first polymer gel which is a polymer of the tertiary nitrogen atom-containing monomer having a polymerizable unsaturated group and a second polymer gel which is a polymer of the quaternary nitrogen atom-containing monomer having a polymerizable unsaturated group.SELECTED DRAWING: Figure 1 【課題】ｐＨによらず、また、他の陰イオンが介在していてもセレンを吸着可能なセレン吸着材、セレン吸着材セット、及び、セレン除去方法を提供する。【解決手段】セレン吸着材は、重合性不飽和基を有する第３級窒素原子含有モノマーと重合性不飽和基を有する第４級窒素原子含有モノマーとの共重合体である高分子ゲルを備える。セレン吸着材セットは、重合性不飽和基を有する第３級窒素原子含有モノマーの重合体である第１の高分子ゲルと、重合性不飽和基を有する第４級窒素原子含有モノマーの重合体である第２の高分子ゲルと、を備える。【選択図】図１
