摘要
研究硝酸钯－硝酸镁基体改进剂对测定痕量铅的基体改进效应，建立了石黯炉平台技术测定痕量铅的实用分析方法。其特征量为８．４Ｐｇ（Ｐｇ／０．００４４Ａ），ＲＳＤ为１．４％～５％，铅回收率为９０％～１１０％。
In this paper the matrix modifiers from palladium nitrate and magnesium nitrate in graphite furnace atomic absorption spectrometry were studied.The determination method of trace amount lead was setup.The feature amount is 8.4 Pg(Pg/0.004 4A),RSD 1.4%～5% and the recovery of lead reached 90%～110%.
