磷钼蓝比色法测定洗衣粉中五氧化二磷含量的不确度评定

Uncertainty Evaluation of P_2O_5 in Laundry Powder

本文对洗衣粉中五氧化二磷含量的不确定度进行评定。通过研究分析磷钼蓝比色法测定洗衣粉中五氧化二磷含量检测过程中不确定度的主要来源,并进行量化和合成。结果表明:洗衣粉中五氧化二磷含量测定的不确定度最主要来源是拟合标准曲线过程引入的不确定度。

This thesis aims at evaluating the uncertainty of P2O5 in laundry powder. The main source of the uncertainty is measured by the analysis of the phosphorus molybdenum blue colorimetric method, and each component of uncertainty is quantified and combined. The results show that the uncertainty in curve fitting process is the main source of the uncertainty of P2O5 in laundry powder.
