纸制品中总砷的测定方法验证

Verification of Determination Method for Arsenic Content in Paper Products

为验证采用原子荧光光谱仪法测定纸制品中砷和无机砷含量的准确性与可靠性,本文对《食品中总砷及无机砷的测定》(GB5009.11-2014)第一篇总砷检测中的方法原子荧光光谱法进行验证。通过对该方法的线性、线性范围、检出限、定量限、精密度及加标回收率6个参数进行验证,说明本检验中心的实验室能展开此方法的检测。

This paper aims to verify the accuracy and reliability of using atomic f luorescence spectrometer to determine the arsenic and inorganic arsenic content in paper products.To verify the atomic f luorescence spectrometer of the second method of GB 5009.11-2014,the linearity,linear range,detection limit,quantitative limit,precision and accuracy of the method were verified,indicating that the laboratory can carry out the test of this method.
