紫外分光光度法测定工作场所空气中对硝基苯胺的测量不确定度评估

Uncertainty Evaluation on Determination of P-nitroaniline in Air of the Workplace by UV Spectrophotometry

空气中的对硝基苯胺用硅胶管采集,采用紫外分光光度法测定对硝基苯胺含量。通过分析测量方法的不确定度来源并对其进行量化,进行不确定度的评定。

P -nitroaniline in air was collected by silicone tube and determined by ultraviolet spectrophotometry . Through analyzing the uncertainty source, measuring uncertainties brought by the method of determination were discovered, quantified and evaluated.
