原子吸收法固体进样测定土壤中镉含量的不确定度评定

Atomic Absorption Spectrometry With Solid Sampling Determination of Cadmium In Soil Content Uncertainty Evaluation

利用原子吸收法固体进样装置测定土壤中镉的含量,并对其测量过程进行了不确定度评定,从而明确了测定时的主要不确定度来源是曲线拟合过程,在测定过程中需进一步改进。

Using atomic absorption spectrometry with solid sampling device for determination of cadmium in soil content, and the meas- urement of uncertainty, the determination of the main sources of the uncertainty of is curve fitting process, in the determination process to be further improved
