摘要
通过对硫酸中铁含量的分析,找出了影响测定结果的各个分量,影响测定结果的分量主要有:分度吸量管的体积、容量瓶的体积、样品的均匀性、样品处理过程以及线性拟合等。作者根据GB/T 601-2002中对化学分析方法测量的不确定度的要求,对ICP——AES法测定硫酸中铁含量的不确定度进行了评定。
The factors that affect the determination result of ferrous content were found by analyzing ferrous content in sulfuric acid.Main factors are as follows: the volume of graduated pipettes and volumetric flasks,sample uniformity,sample processing and linear fitting,etc.This paper assesses the CP-AES method about uncertainty of ferrous content in sulfuric acid,basing on the requirement for the chemical analysis of uncertainty determination in GB/T601-2002.
