| Abstract: | The uncertainty of measurement for the determination of copper in water by Flame Atomic Absorption Spectrometry was evaluated.Many most possible sources of uncertainty of measurement were analyzed,they are :the uncertainty of standard curve,the uncertainty of standard aqua and the uncertainty of standard aqua.The result of repeated tests were that the combined uncertainty was 0.098mg/L and the expanded uncertainty was 0.196mg/L. |
