电化学滴定法确定氟化物熔盐中氧化物量

Determination of Oxide in Molten Fluorides by Electrochemical Titration Technique

摘要: 以K₂NbF₇为探测溶质,应用循环伏安滴定法和循环伏安标量加入法确定FLINAK熔盐中氧化物量。结果表明,FLINAK熔盐中氧化物量等于所加Nb(V)量减去熔盐中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.
