| Abstract: | The uncertainty in measurement of effective copper and zinc in soil by flame atomic absorption spectrometry(FAAS) was evaluated,and the causes of the produced uncertainty in total detection process were analyzed,and the expanded uncertainty and the expression of final outcome were obtained as follows:effective copper was 5.8±0.056mg/kg and effective zinc was 1.14±0.022mg/kg,and the main cause of produced uncertainty was analyzed.The results provide the reliable theory basis for controlling the method for the determination of the effective copper and zinc in soil. |
