火焰原子吸收光谱法测定涂料中的铅

FAAS Determination of Lead in the Dope

采用火焰原子吸收光谱法测定涂料中铅的含量,铅在0.5μg/mL～20.0μg/mL范围内具有良好的线性关系。重点讨论了样品的灰化温度、空心阴极灯灯电流对铅含量测定的影响。测定结果RSD≤3.7％,回收率在99.8％,方法简便,结果准确。

Content of Lead in dope was determined by atomic absorption spectrometry. It had good liner relationship that Lead was over the range of 0.5 ~ 20.0 μg/mL.In this method, RSD was bellow 3.7% and recovery was 99.8% .The method was simple and accurate.
