| 摘 要： | 钒钼共存时在约0．60mol/L的硫酸酸度下，以铜盐为催化剂，硫脲为还原剂，至少30mg钒不干扰钼与硫氰酸盐的显色反应。方法应用于五氧化二钒中钼量的测定。分析结果令人满意。

| Abstract: | Under V-Mo co-existed condition at about 0.6 mol/L acidity of sulfuric acid,using copper as catalyst and sulfocarbamide as reductive agent,at least up to 30 mg vanadium will not disturb the color reaction between molybdenum and thiocyanate.This method gives satisfactory in determination of molybdenum in vanadium pentoxide. |
