电感耦合等离子体发射光谱法测定地下水中锰的不确定度评定

Evaluating on uncertainty of determination of manganese contents in groundwater by inductively coupled plasma atomic emission spectrometry

本文对电感耦合等离子体发射光谱法测定地下水中锰含量的不确定度进行了评定,标准曲线采用双误差拟合法,建立了不确定度评定模型,对测定地下水样品中锰含量的不确定度作了评估。

The uncertainty of determination of manganese contents in groundwater by inductively coupled plasma atomic emission spectrometry（ICP-AES） was evaluated in this paper.The calculating model of double error fitting in the course of standard curve fitting was used,and the mathematical evaluation model for uncertainty was also established.In addition,the uncertainty of the determination of manganese contents in groundwater samples was evaluated.
