Description

Electrochemical reactions and redox properties of actinides such as uranium and neptunium are outlined. The flow electrolysis enables rapid and high-efficiency treatment. It was demonstrated to measure slow processes of actinide redox. Experimental results of electrolysis of actinide ions and the preparation method of oxidation state of the ions based on the fundamental data are described. Mediator reaction and catalysis observed in the process of electrolysis of actinide ions are also explained. (author)

Abstract (Japanese)

ウランやネプツニウムをはじめとした,溶液内で種々の酸化状態をとるアクチノイドイオンの電極反応と酸化還元の特徴を概説する。フロー電解法は迅速かつ高効率な電解が可能で,反応速度の遅い酸化還元の観測にも適用できる。同法を用いて取得したアクチノイドの酸化還元挙動や,これに立脚した酸化状態の迅速調整法を紹介するとともに,電解に伴って発現する溶液内反応や電極上での触媒的還元などについても解説する。(著者)
