原子荧光法测定水中汞的不确定度评估

Evaluation of Uncertainty in Determination of Mercury in Water by Atomic Fluorescence Spectrometry

使用原子荧光法对汞不确定度进行评估,检出限为0.000 01mg/L。通过实际操作得知,在操作过程中,计算与评估来自于标准溶液、工作曲线、重复测量等因素产生的不确定度。

The uncertainty of mercury was evaluated by atomic fluorescence spectrometry.The detection limit was 0.00001 mg/ L.Through the actual operation, in the process of operation, calculation and evaluation from the standard solution, working curve, repeated measurement and other factors of uncertainty.
