石墨炉原子吸收法测定肉制品中镉的过程中的不确定度评定

Evaluation of Uncertainty in Determination of Cadmium in Meat Products by GFAAS

摘要:

本实验参照国家标准GB/T 5009.15-2003[4]《食品中镉的测定》，采用原子吸收石墨炉法测定肉制品中镉的含量。通过对镉的测定进行测量不确定度的评估实验，分析和识别检测过程中不确定度的来源并进行评定，得出影响检测结果的主要因素，为有效地提高检测的准确度提供可靠的理论依据。

Abstract:

Based on GB/T 5009.15-2003, the content of cadmium can be determined with graphite furnace atomic absorption spectrometry. By estimation of uncertainty in measurement of cadmium evaluated, the sources of uncertainty in the detection process were analyzed and identified. After the assessment of uncertainty, the key factors affecting the test results were found. The research provided reliable theoretical basis for effectively improving the detection accuracy.
