摘　　要：以硫脲为还原剂,在优化钼（Ⅴ）与硫氰酸盐显色反应条件的基础上,通过分光光度法测定钼精矿中的钼含量。结果表明,本法测定钼精矿含钼量的相对标准偏差小于5%（n=6）,加标回收率为98.34%~100.30%,置信区间窄,准确度高。Based on the optimized conditions for the chromogenic reaction between Mo（Ⅴ）and thiocyanate,the Mo content of molybdenum concentrate was determined by spectrophotometry with sulfocarbamide as the reducer.The as-tested Mo content in the Mo concentrate is less than 5%（n=6）,standardized recovery is in the range of 98.34%～100.30%.The said method is characterized by narrow confidence interval and high accuracy.
