Abstract

In order to control the maximum levels of As, Cr, Pb, Cd, and Sn in meat products, it is proposed to transfer them to a suspension of 140 mg/mL and use an atomic absorption spectrometer with a graphite furnace, equipped with a probe attachment for a two-stage atomization of the suspension. The working linear range covers 0.2–9 ultimate allowable concentrations. The error is smaller by factors of 2 to 3 than that of the methods with sample dissolution, and it saves at least 12 h in time.

无需样品溶解即可控制肉制品中元素的最终允许浓度的原子吸收控制

摘要

为了控制肉制品中As,Cr,Pb,Cd和Sn的最大含量,建议将其转移到140 mg / mL的悬浮液中,并使用配有石墨炉的原子吸收光谱仪探针附件,用于悬浮液的两阶段雾化。工作线性范围涵盖0.2–9的最终允许浓度。该误差比采用样品溶解方法的误差小2到3倍,并且可以节省至少12 h的时间。
