摘要
本文介绍了在以高铋物料为基体 ,5 %的HNO3 介质中 ,波长 2 17nm处进行火焰原子吸收法测定铅的试验 ,采用标准加入法进行回收率的试验 ,回收率大于 98% ,特征浓度为 0 .0 7μg/ml,结果令人满意 。
This article introduces the test on determining lead content in high bismuth material by flame atomic absorption with a media of 5% HNO 3,and test of recovery with standard dosing method. The recovery achieved is higher than 98%, and the typical concentration is 0.07μg/mL. This satisfactory result can meet the requirement of furnace sample analysis.
