合成氨脱碳液中五氧化二钒测定方法的改进

Improvement of Determination Method of Vanadium Pentoxide in Decarburizing Solution of Ammonia

采用分光光度法取代硫酸亚铁滴定法,用于测定脱碳液中的五氧化二钒含量,有较高的回收率,结果准确可靠。

Ferrous sulfate titration was replaced with spectrophotometry to determine the vanadium pentoxide in decarburizing solution and this method had high recovery.
