摘要
依据皮革和毛皮重金属检测标准《GB/T 22930-2008皮革和毛皮化学试验重金属含量的测定》的规定,通过微波消解对样品进行前处理,在ICP上测定其铬元素的含量。对整个实验过程中各个不确定度的分量进行评定合成,给出合成不确定度和扩展不确定度并确定不确定度的主要来源。
Based on the provisions of 《GB/T 22930-2008 Leather and fur-chemical lesls-determinalion of heavy metal content》 , for prelreatment of the sample by microwave digestion, determining the content of chromium element in ICP. To assess the synthesis of each component of uncertainty in the process of the whole experiment, give the synthetic uncertainly and expanding uncertainty, and finally determine the main source of uncertainty.
