摘要
以提高测量的准确度为目标,依据JJF 1059.1-2012《测量不确定度评定与表示》,对滴定法测定槟榔中钙离子含量的不确定度进行评定。通过建立数学模型对钙离子检测过程中不确定度的来源进行分析,可知其不确定度来源主要来自测量重复性、样品的称量、与样品滴定过程等。
According to JJF 1059.1-2012 Evaluation and Expression of Uncertainty in Measurement,the evaluation of the uncertainty of titrimetric determination of calcium ion in Areca Catechu L was analyzed.The source of uncertainty in the process of calcium ion detection was analyzed by establishing a mathematical model.The sources of uncertainty were mainly from measurement repeatability,sample weighing and sample titrimetric process.
