摘 要: 采用循環(huán)伏安法和計(jì)時(shí)電位法研究了鈧離子在1043K下、LiF-NaF體系中銀電極上的陰極還原過程。結(jié)果表明，Sc3+在Ag電極上的還原過程是可逆的簡(jiǎn)單電荷傳遞的三電子反應(yīng)，陰極過程受擴(kuò)散控制。

Abstract:The reduction mechanism of Sc3+ ion on Ag electrode in LiF-NaF system at 1043 K was investigated with the cyclic voltammetry and chronopotentiometry. The results showed that the cathode reduction reaction is the reversible process with a simple 3-electron transfer, and is controlled by diffusion.
