電化學滴定法確定氟化物熔鹽中氧化物量

Determination of Oxide in Molten Fluorides by Electrochemical Titration Technique

摘要: 以K₂NbF₇為探測溶質,應用循環伏安滴定法和循環伏安標量加入法確定FLINAK熔鹽中氧化物量。結果表明,FLINAK熔鹽中氧化物量等于所加Nb(V)量減去熔鹽中Nb₇^2-量。

Abstract: A cyclic vollammelry is emploied to determine the amount of oxide in FLTNAK melt. K₂NbF₇ is a good litrant. The amount of oxide is also determined by a vollammetric standard addition method. The results show that the amount of oxide in FLINAK melt is equal to the added amount of Nb(V) minus the amount of NbF₇^2- in the melt.
