摘要
叙述了分光光度法测定脱硫废催化剂中钼，在硫酸条件下，用硫脲将六价钼还原成五价钼，然后以硫氰酸钾为显色剂用分光光度法测定，选择了最佳测定条件，样品测定结果ＭｏＯ３＝５．６５％，方法精确度０．
Determination of molybdenum in desulfurized waste catalyst by spectrophotometry is introduced.In the presence of sulfuric acid,Mo() is reduced to Mo() by thiourea,then KSCN is used as chromogenic reagent for determinating molybdenum by spectrophotometry.The optimum conditions of determianation are studied.The result of sample is MoO3=565%.The precision of method is 006.
