摘要
根据EURACHEM/C ITAC 2000中的规定评定了ICP-AES法测定油漆中总铅含量的不确定度。结果表明,标准曲线拟合线性方程、标准工作液配制过程、样品重复性分析及消化过程中消化回收率是不确定度的主要来源。油漆涂层中的可溶性铅的检测结果可表示为:(162.7±19.0)mg/kg(k=2)。
The uncertainty of determination of total lead content in paint by ICP - AES was calculated according to the guide given in EURACHEM/CITAC 2000. The results showed that the fitted linear regression equation for the calibration curve, the preparation of standard solution, repetitive analysis of samples and digestive recovery in digestive process were the main sources of uncertainty. The determination of total lead content in paint was (162.7±19.0)mg/kg(k=2).
