Outline of Annual Research Achievements

本研究では、放射性核種の環境挙動に及ぼす様々な素過程について研究を行った。特にここでは、放射性廃棄物に含まれる元素として重要なモリブデンやウランの挙動に関する研究を行った。モリブデンについては、鉄マンガン酸化物への吸着に関する研究を行い、特に天然での海底鉄マンガン酸化物への吸着に関する研究を行い、陰イオンでも結合が安定であればマンガン酸化物に濃集することを示した。また海底鉄マンガン酸化物中の水酸化鉄とマンガン酸化物はそれぞれ微量元素のホスト相として独立に機能していることが示唆された。またウランについては、スメクタイト中のFe3+をFe2+に還元させて生成したFe(II)を含むスメクタイトにより、U(VI)がU(IV)に還元され、ウランは固相中にUO2として分配されると推定された。層構造中のFe(II)/Fe(III)比が大きいほどU(IV)/U(VI)比が大きくなる傾向がみられ、ネルンストの式で標準電位と[酸化種]/[還元種]比の対数値の和で規定される酸化還元ポテンシャルにより、この還元反応が駆動されると示唆された。またpHが高いほどU(IV)の生成割合が高いことも認められ、これはpHの増加と共にUO2の安定性が高まるためと考えられる。この反応の前後での粘土鉱物中のFe(III)とFe(II)の局所構造をEXAFSから調べた結果、いずれも6配位サイトに存在すると考えられるものの、近接酸素との距離はFe(III)からFe(II)に変化する際に、通常の化合物にみられるほど長くはならなかった。これは、構造的にFe(II)が不安定なサイトに保持されることを示し、これが粘土鉱物中のFe(II)の還元力の要因になっている可能性がある。これまでこうした粘土鉱物の層構造中のFe(II)による還元反応について、XAFS法を用いた検討は十分になされておらず、本研究はその機構解明に寄与する。
