摘　　要：本文从标准曲线拟合、黄磷标准溶液配制、重复性、标准系列溶液配制、水样量取等五个方面对钼-锑-抗分光光度法测定水中黄磷的不确定度进行分析计算,找出影响不确定度的因素,如实反应测量的置信度和准确性。The article discussed the uncertainty of determination of yellow phosphorus in water by spectrophotometry from the following five aspects： curve fitting,standard solution of yellow phosphorus confecting,repeatability,a continuous series standard solution of yellow phosphorus confecting and sampling,water measure.Then we found the main influence factor of the uncertainty according the data which also responsed the confidence level and accuracy of this method.
