电感耦合等离子体质谱法测定生漆漆器中的铅铬

Determination of Lead and Chromium in Raw Lacquer and Its Lacquer by Inductively Coupled Plasma Mass Spectrometry

本文重点研究了两种生漆漆器样品中铅、铬测定的前处理方法。采用盐酸消煮样品,用电感耦合等离子体质谱法(ICP-MS)测定,在选定的实验条件下,用钪、铼做为内标元素,绘制铅、铬标准曲线,其线性相关系数(R)分别为0.9997和0.9994,方法测定下限为0.1~0.4μg/L,相对标准偏差RSD为2.8%~3.1%,加标回收率为99%~104%。

The paper determination of Pb and Cr in raw lacquer and its lacquer by ICP-MS.The sample of hydrochloric acid was used,Under the selected experimental conditions,Scandium and rhenium are used as internal standard elements,the correlation coefficients of calibration curves for lead and chromium were 0.9997 and 0.9994.The low limit of determination was 0.1~0.4μg/L.The RSD of determination results were 2.8%and 3.1%.The recoveries were between 99% and 104%.
