四苯硼酸钠重量法测定光卤石中钾含量结果的不确定度

Determination of the Uncertainty in Measuring Potassium Content in Carnallite by Sodium Tetraphenynlborate Weight Method

讨论四苯硼酸钠重量法测定光卤石中钾含量测量不确定度的影响因素,对测量过程中的测量不确定度分量进行了分析和计算。求出光卤石中钾含量测量结果的标准不确定度为0.35×10-3,扩展不确定度为0.70×10-3,并对测量结果进行了表述。

Influence factors of the uncertainty in measuring potassium content in carnallite by sodium tetraphenynlborate weight method were discussed; components of the uncertainty were analyzed and calculated. The results show that the measurement standard uncertainty is 0.35 ×10^-3, the expanded uncertainty is 0.70 ×10^-3.
