| 摘 要： | 目的进行离子色谱法测定水中溴酸根离子含量的不确定度分析。方法按照测定程序，建立数学模型，根据不确定度传播规律，计算出相对和绝对扩展不确定度。结果水样中溴酸根离子的浓度为0．0638mg／L时，其绝对扩展不确定度为±0．0031mg/L。结论该方法在实际工作中有较强的应用价值。

| Abstract: | [ Objective] To analyze uncertainty of Bromate ion determination in water by ion chromatography. [ Methods ] According to procedures, mathematic model was established , then the relative and the absolute expanded uncertainties were calculated based on the spreading regulation of uncertainty. [ Results] When the concentration of Bromate in water arrived 0.0638 mg/L, the expand- ed uncertainty was ±0. 0031 mg/L. [ Conclusion]This method can produce large application value in practical work. |
