摘要
对Ag-DDTC分光光度法测定硫铁矿和硫精矿中砷含量的不确定度进行了评定,分析了测量不确定度的来源,包括试样称重引入的不确定度、标准溶液浓度引入的不确定度、试样分取体积引入的不确定度、标准曲线拟合引入的不确定度等。通过评定,标准曲线拟合引入的不确定度最大。
In this paper, the uncertainty of determination of arsenic content in pyrite and sulphur concentrate by Ag- DDTC spectrophotometry method was evaluated. The main sources of uncertainty were analyzed, including sample weighing the standard solution concentration, the volume and the standard curve fitting to introduce uncertainty, etc. Through the evaluation, the uncertainty of standard curve fitting is introduced into the larger.
